When probing multiple interfaces (according to the result from the
board_boot_order function), we need to ensure that only valid FIT
images are considered and disable the fallback to assuming that
a raw (binary-only) U-Boot image is loaded (to avoid hangs/crashes
from jumping to random content loaded from devices that in the
probing order which do not contain a valid image).
When the SPL_LOAD_FIT configuration option is enabled, the new
SPL_LOAD_FIT_ONLY option becomes available to disable such fallback
paths.

We assume that any (i.e. the first) FDT contained fits our board
and simply return a positive match every time.

As SPL can probe multiple interfaces, we can let it do the work for
FIT images and simply provide the board_boot_order hook.
This mechanism is fully implemented for sun9i (i.e. A80) platforms
and falls back to the old mechanism of determining a single boot
device for older/other platforms for now.

In raw mode a full sector is to be read even if image covers part of
a sector. Number of sectors are calculated as ROUND_UP(size)/sec_size by FIT
framework. This calculation assumes that image is at the 0th offset of a sector,
which is not true always in FIT case. So, include the image offset while
calculating number of sectors.

The next stage boot loader image and the selected FDT can be post-
processed by board/platform/device-specific code, which can include
modifying the size and altering the starting source address before
copying these binary blobs to their final destination. This might be
desired to do things like strip headers or footers attached to the
images before they were packaged into the FIT, or to perform operations
such as decryption or authentication. Introduce new configuration
option CONFIG_SPL_FIT_IMAGE_POST_PROCESS to allow controlling this
feature. If enabled, a platform-specific post-process function must
be provided.

When no DTB can be matched successfully to the board that's being used
a list of available FIT-embedded DTBs will be output to the console for
diagnostic purposes. But rather than the contents of the "description"
FDT property a non-existent property was accessed and as a result "NULL"
was output instead of the actual name(s) of the DTB(s). Fix this issue
by using the correct property which is also the exact same property
that's used earlier during the actual board matching process.

we need to do board specific things that we can't select only based on
the CPU flavor. So we introduce the Kconfig option to select a specfic
sunxi board

This adds a DTS and a defconfig for the A80-Q7 (a system-on-module
compatible with the Qseven form-factor developed and supported by
Theobroma Systems).

Throughput tests have shown the sunxi_mmc driver to take over 10s to
read 10MB from a fast eMMC device due to excessive delays in polling
loops.
This commit restructures the main polling loops to use get_timer(...)
to determine whether a (millisecond) timeout has expired. We choose
not to use the wait_bit function, as we don't need interruptability
with ctrl-c and have at least one case where two bits (one for an
error condition and another one for completion) need to be read and
using wait_bit would have not added to the clarity.
The observed speedup in testing is greater than 10x (e.g. a 10MB write
decreases from 9.302s to 0.884s).

On A80 boards, both a AXP809 (primary) and AXP806 (secondary)
PMIC are found. The AXP806 supplies the Cortex-A15 cores with
a poly-phase supply to deliver up to 10A of total power.
When used in the slave configuration, the AXP806 needs a write
to the REGADDR_EXT register to configure it to work on the same
RSB bus as the primary PMIC.
|
|
Implement support for the AXP809 PMIC that is used on A80 platforms
as the primary PMIC and powers most peripherals and the CPUA (Cortex-A7)
cluster. A AXP806 is usually the slave PMIC, which will provide the
power for the CPUB (Cortex-A15) cluster.
The default voltage settings have been chosen to be safe values for a
Optimus, Cubieboard and A80-Q7. These changes are validated against the
A80-Q7 module.

On sun9i, the GTBUS manages transaction priority and bandwidth
for multiple read ports when accessing DRAM. The initialisation
mirrors the settings from Allwinner's boot0 for now, even though
this may not be optimal for all applications (e.g. headless
systems might want to give priority to IO modules).
Adding a common callout to gtbus_init() from the SPL clock init
with a weakly defined implementation in sunxi/clock.c to fallback
to for platforms that don't require this.
|
|
This adds DRAM initialisation code for sun9i, which calculates the
appropriate timings based on timing information for the supplied
DDR3 bin and the clock speeds used.
With this DRAM setup, we have verified DDR3 clocks of up to 792MHz
(i.e. DDR3-1600) on the A80-Q7 using a dual-channel configuration.

The description was borrowed from kernel. "tristate" type was changed
to "bool" (I believe we don't support modules for u-boot yet, right?).
CONFIG_USB_GADGET requires CONFIG_USB to be defined too, so add it along
as well.
Definitions were added to defconfig files in a way that
"make savedefconfig" generates exactly the same file as used defconfig.
