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.

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).

Our initial clock setup had been based on the basic_bootloader (boot0),
but differed from what Allwinner used in their SDK in 'u-boot-2011.09'.
To improve compatibility, we now switch to the same clocking they have
used.

The chip-id on the sun9i resides in the SID block, but at an offset
from what we'd expect with older variants.

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.

Always select OF_BOARD_SETUP on sunxi, rather then having it in almost
all our defconfigs. This also fixes it missing from some recently
added defconfigs.
This commit also modifies our ft_board_setup() to not cause warnings
when CONFIG_VIDEO_DT_SIMPLEFB is not set, since we will now always
build it.

cpu_eth_init is no longer called for dm enabled eth drivers, this
was causing the sunxi gmac eth controller to no longer work in u-boot.
This commit fixes this by calling the clock, reset and pinmux setup
function from s_init() and enabling the phy power pin (if any) from
board_init().
The enabling of phy power cannot be done from s_init because it uses dm
and dm is not ready yet at this point.
Note that the mdelay is dropped as the phy gets enabled much earlier
now, so it is no longer needed.

I've had this one a23 tablet which would not boot and I've finally
figured out what the problem is by looking at the released boot0 code,
it seems the magic sram controller poke which we need to do in s_init()
depends on the revision of the a23.
Specifically this change is needed to get the A23 SoC I have with the
following serial to boot: "E6071AB 26Y7".

For ARM32 architecture, CONFIG_DEBUG_LL is available for early
low-level debugging (and actually UniPhier 32bit SoCs use it), but
ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART
is available as an architecture-independent debug facility.
This commit supports it on all the UniPhier SoCs (including the new
ARMv8 SoCs), which is very useful for new SoC bringups.

These commands are not necessarily needed for usual operations
(they are useful in case of DDR memory trouble), but enabling them
by default would be nice in terms of the compilation test coverage.
They are small enough, so limited impact on the memory footprint.

Due to some hardware guy's awful work, this version is not compatible
with v3.6: the logic of BIT(0) of the reset logic is inverted! (and
v3.6.10 is horribly wrong in multiple ways), but this is what we have
to solve now.
The v3.6 expects 0x0000 set to the register for reset de-assertion,
while v3.6 does 0x0001.
This commit (ab)uses another bug of v3.6.10 to work around the issue.
The UniPhier System Bus is a 16-bit bus, which this support card is
connected to. A 32-bit write to the bus (writel() function call) is
divided into two 16-bit write transactions, with LSB the first. What
is amazing for v3.6.10 is that access to address 4N + 2 goes to 4N
(Jesus Christ!).
For clarification, things are like this:
writel(0x00010000, MICRO_SUPPORT_CARD_RESET);
is done with two bus transactions as follows
[1] write 0x0000 to address MICRO_SUPPORT_CARD
[2] write 0x0001 to address MICRO_SUPPORT_CARD + 2
For v3.6, [1] is written to the register and [2] is correctly ignored
because there is nothing at the address MICRO_SUPPORT_CARD + 2. This
is what we expect.
For v3.6.10, [1] is written to the reset register and then [2] is
over-written to the same register due to the bus access bug.
For the latter, it produces a glitch signal to the BIT[0], so the
device state is lost due to the reset pulse. This solution only
works for the start-up code.
