The transfer request exceeding 4032KB (the maximum number of TRBs per
TD * the maximum size of transfer buffer on TRB) fails on xhci host
with timed out error or babble error state. This failure occurs when
accessing large files on USB mass-storage. Currently with xhci as well
as ehci host, the driver requests maximum 30MB (65536 blks * 512 byte)
to storage at once. However, xhci cannot handle this request because
of the reason mentioned above, even though ehci can handle this. Thus,
transfer request larger than this size should be splitted in order to
limit the length of data in a single TD.
Even though the single request is splitted into multiple requests,
the transfer speed has affected insignificantly in comparison with
ehci host: 22.6 MB/s on ehci and 22.3 MB/s on xhci for 100MB tranfer.

The BROM supports forcing it to enter download-mode, if an appropriate
result/cmd-word is returned to it. There already is a series to
support this in review, so this prepares the (newly C-version) of the
back-to-bootrom code to accept a cmd to passed on to the BROM.
All the existing call-sites are adjusted to match the changed function
signature.

For the RK3188, the BROM will attempt to load up the first stage
image (SPL for the RK3188) in two steps: first 1KB to offset 0x800
in the SRAM and then the remainder to offset 0xc00 in the SRAM.
It always enters at 0x804, though.
With this changeset, the RK3188 boot removes the TPL (stub) stage and
builds a single SPL binary that utilizes the early back-to-bootrom via
the boot0-hook.
Consequently, the passing of the saved boot params via pmu->os_reg[2]
is also removed.

- [added in v2] chain back_to_bootrom calls for SPL, first returning

Series-changes: 4
- after merging the 'back-to-bootrom' series with the 'boot0-hook'
series, this drops the TPL stub and builds only a single SPL image
that uses the 'early back-to-bootrom' logic originally implemented
by Pawel for the RK3066.
- changes the SPL_STACK_BASE to +0x800 (from +0x804), as the boot0
hook already reserves the space for the SPL magic (previously
inserted by mkimage)

The back-to-bootrom implementation for Rockchip has always relied on
the stack-pointer being valid on entry, so there was little reason to
have this as an assembly implementation.
This provides a new C-only implementation of save_boot_params and
back_to_bootrom (relying on setjmp/longjmp) and removes the older
assembly-only implementation.

rockchip: back-to-bootrom: replace assembly-implementation with C-code
Recent discussions confirmed (what the code always assumed): the
Rockchip BROM always enters U-Boot with the stack-pointer valid
(i.e. the U-Boot startup code is running off the BROM stack).
We can thus replace the back-to-bootrom code (i.e. both the
save_boot_params and back_to_bootrom implementations) using C-code
based on setjmp/longjmp. The new implementation is already structured
to allow an easy drop-in of Andy's changes to enter download-mode when
returning to the BROM.
This turned out to require a some tweaking to system.h (making sure
that the prototype for save_boot_params_ret is visible for A64)and
start.S (so binutils knows that this is a possible function entry and
it can correctly insert A32-to-Thumb transitions) and taking the axe
to setjmp.h (which created quite a few issues with it not expecting
A32/T32/Thumb call-sites and some fragility from GCC being smart about
the clobber-list of the inline assembly... which led to r9 not being
saved or restored).
END
|
|
The previous setjmp-implementation (as a static inline function that
contained an 'asm volatile' sequence) was extremely fragile: (some
versions of) GCC optimised the set of registers. One critical example
was the removal of 'r9' from the clobber list, if -ffixed-reg9 was
supplied.
To increase robustness and ensure PCS-compliant behaviour, the setjmp
and longjmp implementation are now in assembly and closely match what
one would expect to find in a libc implementation.

- converted setjmp/longjmp from inline-assembly to separate .S files
to improve predicatability if emitted code
|
|
As no '.type' was set for save_boot_params_ret in start.S, binutils
did not track whether it was emitted as A32 or T32. By properly
marking save_boot_params_ret as a potential function entry, we can
make sure that the compiler will insert the appropriate instructions
for branching to save_boot_params_ret both for call-sites emitted as
A32 and T32.

- tracked the root-cause why no interwork branch was emitted and fixed
it using a '.type'-directive in start.S to mark save_boot_params_ret
as a (possible) function-entry.

The save_boot_params_ret() prototype (for those of us, that have a
valid SP on entry and can implement save_boot_params() in C), was
previously only defined for !defined(CONFIG_ARM64).
This moves the declaration to a common block to ensure the prototype
is available to everyone that might need it.

Some Rockchip BROM versions (e.g. the RK3188 and RK3066) first read 1KB data
from NAND into SRAM and executes it. Then, following a return to bootrom, the
BROM loads additional code to SRAM (not overwriting the first block read) and
reenters at the same address as the first time.
To support booting either a TPL (on the RK3066) or SPL (on the RK3188) using
this model of having to count entries, this commit adds code to the boot0
hook to track the number of entries and handle them accordingly.
Adding this few lines of code here meets these conditions.

Rockchip SoCs bootrom design is like this:
- First 2KB or 4KB internal memory is for bootrom stack and heap;
- Then the first 4-byte suppose to be a TAG like 'RK33';
- The the following memory address end with '0004' is the first
instruction load and running by bootrom;
Let's use the boot0 hook to reserve the first 4-byte tag for all
the Rockchip SoCs.

The boot0 hook on ARM does not insert its payload before the vector
table and mismatches its comments and the usage on ARM64. To fix
this, we change the boot0-hook semantics on ARM to match those on
ARM64:
(1) if a boot0-hook is present it is inserted at the start of
the image
(2) if a boot0-hook is present, emitting the ARM vector table
(and the _start) symbol are suppressed in vectors.S and
the boot0-hook has full control over where and when it
wants to emit these

spl: atf: update booting images via ATF to use info from FIT images
A number of things about how we boot the RK3368 and RK3399 through ATF
are less than ideal today, especially when considering future
platforms that will follow a similar boot concept:
- the auto-detection of images from the FIT images was limited (i.e.
the start address of the BL33 image could not automatically retrieved)
- no implementation for the platform-specific parameters existed (and
there is a danger that we'll end up with highly different, proprietary
platform parameters for different SOCs and boards, even though the
ATF code base already has FDT support)
This series tries to put us into a better position to support various
boot scenarios (e.g. loading an OPTEE from the FIT image; and: booting
a Linux kernel via ATF) in the future... and it establishes the FDT as
a mechanism to pass boot-info to later stages.
For a practical example, refer to how we use this on the RK3399-Q7:
* the ATF can read the full U-Boot's FDT to determine how to best issue
a cold-reset for the board
* we inject information on where we loaded the M0 firmware into the
same FDT that is now visible to the ATF, so the ATF can relocate it
to its final destination---and we no longer need to overwrite parts
of the SPL binary during bootup
Note that there are still some limitations (e.g. the support for
passing OPTEE as a BL3-2, is not in this version ... and there isn't
support for booting Linux directly via ATF yet, either), but these can
now be plugged cleanly into this infrastructure.

This defconfig update makes use of the new features:
* CONFIG_ROCKCHIP_SPL_RESERVE_IRAM is now set to 0, as there is no
overlap between the M0 firmware and the ATF (we load this to DRAM
and relocate it to its final location within the ATF)
* tracks the ATF_SUPPORT -> ATF renaming

This commit updates the .its file for the RK3399-Q7 to use the new
features and demonstrates how to use those:
* it marks the ATF as the 'firmware'
* it tracks the OS-type for U-Boot and ATF
* it loads the PMU (M0) firmware to DRAM and records the location
to /fit-images (where our ATF reads it from)
With the handoff of the next-stage FDT to ATF in place, we can now use
this to pass information about the load addresses and names of each
loadables to ATF: now we can load the M0 firmware into DRAM and avoid
overwriting parts of the SPL stage. This is achieved by changing our
.its-file to use an available area of DRAM as the load-address.

This adds a new interface spl_invoke_atf() that takes a spl_image_info
argument and then derives the necessary parameters for the ATF entry.
Based on the additional information recorded (into /fit-images) from
the FIT loadables, we can now easily locate the next boot stage.
We now pass a pointer to a FDT as the platform-specific parameter
pointer to ATF (so we don't run into the future headache of every
board/platform defining their own proprietary tag-structure), as
FDT access is already available in ATF.
With the necessary infrastructure in place, we can now update the
support for the ARM Trusted Firmware to dispatch into the
spl_invoke_atf function only if a IH_OS_ARM_TRUSTED_FIRMWARE image is
loaded.

If a FDT was loaded (e.g. to append it to U-Boot image), we store it's
address and record information for all loadables into this FDT. This
allows us to easily keep track of images for multiple privilege levels
(e.g. with ATF) or of firmware images preloaded into temporary
locations (e.g. PMU firmware that may overlap the SPL stage).

During the loading of more complex FIT images (e.g. when the invoked
next stage needs to find additional firmware for a power-management
core... or if there are multiple images for different privilege levels
started in parallel), it is helpful to create a record of what images
are loaded where: if a FDT is loaded for one of the next stages, it
can be used to convey the status and location of loadables.
This adds a fdt_record_loadable() function that can be invoked to
record the status of each loadable below the /fit-images path.

To better support bootin through an ATF or OPTEE, we need to
streamline some of the logic for when the FDT is appended to an image:
depending on the image type, we'd like to append the FDT not at all
(the case for the OS boot), to the 'firmware' image (if it is a
U-Boot) or to one of the loadables (if the 'firmware' is an ATF, an
OPTEE, or some other image-type and U-Boot is listed in the
loadabled).
To achieve this goal, we drop the os_boot flag and track the type of
image loaded. If it is of type IH_OS_U_BOOT, we append the FDT.

When loading a full U-Boot with detached device-tree using the SPL FIT

To boot on ARMv8 systems with ARM Trusted Firmware, we need to
assemble an ATF-specific parameter structure and also provide the

image, this adds the necessary definitions.
