dbada49554 arm: rmobile: Fix off-by-one error in cpuinfo
In rmobile_cpuinfo_idx() there is an off-by-one error in accessing the
rmobile_cpuinfo array.

At the end of the loop, i is equal to the array size, i.e.
rmobile_cpuinfo[i] accesses one entry past the end of the array. The
last entry in the array is a fallback value so the loop should count to
ARRAY_SIZE(rmobile_cpuinfo) - 1 instead, this will leave i equal to the
index of the fallback value if no match is found.

Originally, exporting the ATF_LOAD_ADDR was required, but since binman has

The ATF address is now passed via binman.

fe85863086 armv8: Skip PIE in SPL due to load alignment fault.
When PIE is enabled in start.S, u-boot/-spl use __rel_dyn_start
and _rel_dyn_end symbol to be loaded to and executed at a
different address than it was linked at.

u-boot-spl.lds is used in SPL build, but relocation information
section(.rela*) were discarded.
In line number 80 in arch/arm/cpu/armv8/u-boot-spl.lds
 /DISCARD/ : { *(.rela*) }

If PIE enabled in SPL, __rel_dyn_start which is defined as
.rel_dyn_start in sections.c will be apended to the end of
.bss section.

In our ASPEED case, size of .bss section would let .rel_dyn_start
without 8-byte alignment, leading to alignment fault when
executing ldp instuction in pie_fix_loop.

726a802fda arm: Use builtins for ffs/fls
Since ARMv5, the clz instruction allows for efficient implementation of
ffs/fls with builtins. Until ARMv7 (with Thumb-2), this instruction is
only available in ARM mode. LTO makes it difficult to force specific
functions to be in ARM mode, as it is effectively a form of very
aggressive inlining. To work around this, fls/ffs are implemented in
assembly for ARMv5 and ARMv6 when compiling U-Boot in Thumb mode.
Overall, this saves around 75 bytes per call.

This code is synced with v5.15 of the Linux kernel.

Use a recent coreboot build for this test.

The coreboot commit is:

   6f5ead14b4 mb/google/nissa/var/joxer: Update eMMC DLL settings

This is build with default settings, i.e. QEMU x86 i440fx/piix4

Add some documentation as to how to update it next time.

9e8cbea1a7 serial: stm32: extend TC timeout
Waiting 150us TC bit couldn't be enough.

If TFA lets 16 bits in USART fifo, we has to wait 16 times 87 us (time
of 10 bits (1 byte in most use cases) at a baud rate of 115200).

c9678850bd ARM: dts: stm32: Switch DWMAC RMII clock to MCO2 on DHCOM
The DHCOM SoM has two options for supplying ETHRX clock to the DWMAC
block and PHY. Either (1) ETHCK_K generates 50 MHz clock on ETH_CLK
pad for the PHY and the same 50 MHz clock are fed back to ETHRX via
internal eth_clk_fb clock connection OR (2) ETH_CLK is not used at
all, MCO2 generates 50 MHz clock on MCO2 output pad for the PHY and
the same MCO2 clock are fed back into ETHRX via ETH_RX_CLK input pad
using external pad-to-pad connection.

Option (1) has two downsides. ETHCK_K is supplied directly from either
PLL3_Q or PLL4_P, hence the PLL output is limited to exactly 50 MHz and
since the same PLL output is also used to supply SDMMC blocks, the
performance of SD and eMMC access is affected. The second downside is
that using this option, the EMI of the SoM is higher.

Option (2) solves both of those problems, so implement it here. In this
case, the PLL4_P is no longer limited and can be operated faster, at
100 MHz, which improves SDMMC performance (read performance is improved
from ~41 MiB/s to ~57 MiB/s with dd if=/dev/mmcblk1 of=/dev/null bs=64M
count=1). The EMI interference also decreases.
