Code supports board detection based on information available in EEPROM in
legacy or FRU format. But this is not enough for emulation and simulation
systems which are lacking these identification EEPROMs. But SOC itself has
normally registers for SOC identification. Based on them it is possible to
compose detected name. That's why prepare infrastructure in common location
for SOC platform detection which is called before board platform detection.
SOC platform detection shouldn't detect real silicon and should fallback to
current existing mechanism to identify boards based on EEPROMs.

As the flash sizes are increasing day by day, QSPI can have devices of
size > 512MB. In qspi driver we are trying to read all the data at once
using DMA.
The DMA descriptor destination size is only 29bits long.
QSPIDMA_DST_SIZE 0xFF0F0804
BITS: 1:0 Reserved to keep word alignment
BITS: 28:2 Number of 4-byte words the DMA will transfer
BITS: 31:29 Reserved: Returns 0 when read, writes ignored
So we can only transfer data of 0x1FFFFFF0(512MB minus 4bytes) bytes.
Anything above will overflow this register and will ignore higher bits
above 29 bits.
Change the DMA functionality if the requested size is greater than or
equal to 512MB to read 256MB chunks.

ENV_OFFSET_REDUND config is by default set to 0 for flashes. Saving the env
variables is overwriting data at 0 offset, which is wrong. So add default
redund env offset for Zynq, ZynqMP, Versal and microblaze platforms.
Configured ENV_OFFSET_REDUND offsets by ENV_OFFSET + (2 * ENV_SIZE).
In case of versal, we configured ENV_OFFSET_REDUND at 0x7F00000 instead
of 0x7F80000. As BOOT_SCRIPT_OFFSET is already configured at 0x7F80000.
Added ENV_OFFSET_REDUND in Kconfig for microblaze due to dependency of

Commit 5bb2c550b1 ("arm: mvebu: Move internal registers in
arch_very_early_init() function") moved code from file cpu.c to lowlevel.c,
which moves Marvell internal registers from address INTREG_BASE_ADDR_REG to
SOC_REGS_PHY_BASE.
But the steps describing how to do it correctly were documented only in
older U-Boot versions and commit cefd764222 ("arm: mvebu: Fix internal
register config on A38x") probably unintentionally removed important
details about MMU from code comments around.
Commit 5bb2c550b1 ("arm: mvebu: Move internal registers in
arch_very_early_init() function") implemented code movement according to
(now incomplete) comments which resulted in semi-broken code.
The result is that I-cache is currently disabled for all Armada 38x boards
and maybe there are some other (unreported / undetected) issues.
Reimplement it correctly. First flush all caches, then disable MMU and L2
cache and then move Marvell internal registers. There is no need to
explicitly disable I-cache.
After this change lzmadec command with lzma image of 0x7000000 bytes is
doing decompression just 5 seconds. Before this change it was 30 seconds.
To make lowlevel.S code more readable, extend asm/pl310.h header file to be
compatible with assembler and use macros from this file.

For some unknown reason when L2 cache is disabled on Armada 385 then loadb,
loadx and loady commands do not work with higher baudrates than 115200
(they just abort transfer) and lzmadec command with lzma image of size
0x7000000 (maybe even smaller, we tested this one) is doing decompression
for more than 2 minutes. After enabling L2 cache decompression takes only
30s and loadb, loadx and loady are stable and working fine.
git bisect identified problematic commit 3308933d2f ("arm: mvebu: Avoid
reading MVEBU_REG_PCIE_DEVID register too many times"). Before this commit
above issues were not present.
But investigation showed that above issue was possible to reproduce also by
reverting that commit and forcing compiler to do inline optimization of
mvebu_soc_family() function. Which seems that the root of this issue is in
caches and position of instruction of segments. So currently it is unknown
what is or was broken, but code movement, code inlining or other compiler
optimization triggered it.
Commit 3e5ce7ceeb ("arm: mvebu: Enable L2 cache on Armada XP") mentioned
that enabling L2 cache on Armada XP improved performance and that Armada
38x has L2 disabled (which is default state) and if needed it has to be
enabled in separate patch. As enabling L2 cache also improve performance
on Armada 38x, enable it.
Note that Aurora cache in no outer mode is available only on Armada XP,
hence it is not touched for Armada 38x code.
