When a previous phase of U-Boot has run we need to adjust the init of
subsequent states to avoid messing up the CPU state.
Add a new version of the start logic for SPL, when it boots from TPL
(start_from tpl.c) and a new version for U-Boot when it boots from SPL.

At present the debug UART is set up in sdram.c which is not the best place
since it has nothing in particular to do with SDRAM. Since we want to

At present, for broadwell, SDRAM is always set up in U-Boot proper since
the 64-bit mode (which uses SDRAM init in SPL) is not supported.
Update the code to allow SDRAM init in SPL instead so that U-Boot proper
can be loaded into SDRAM and run from there. This allows U-Boot to be
compressed to reduce space, since it is not necessary to run it directly
from flash. It could later allow us to support 64-bit U-Boot on broadwell.

Add board code and DTs for Renesas RZ/A1 SoC-based GR-Peach,
which is a cheap development platform with RZ/A1H SoC. The
DTs are imported from Linux 5.0.11, commit d5a2675b207d .
Currently supported are UART, ethernet and RPC SPI. The board
can be booted from RPC SPI by writing the u-boot.bin binary
to the beginning of the SPI NOR, e.g. using the "sf" command.
The board can also be booted via JTAG by setting text base to
0x20020000, loading u-boot.bin there via JTAG and executing it
from that address.

On AM654 SoC(arm64) which is IO coherent and has L3 Cache, cache
maintenance operations being done to support non-coherent platforms
causes issues.
For example, here is how U-Boot prepares/handles a buffer to receive
data from a device (DMA Write). This may vary slightly depending on the
driver framework:
Start DMA to write to destination buffer
Wait for DMA to be done (dma_receive()/dma_memcpy())
Invalidate destination buffer (invalidate_dcache_range())
Read from destination buffer
The invalidate after the DMA is needed in order to read latest data from
memory that’s updated by DMA write. Also, in case random prefetch has
pulled in buffer data during the “wait for DMA” before the DMA has
written to it. This works well for non-coherent architectures.
In case of coherent architecture with L3 cache, DMA write would directly
update L3 cache contents (assuming cacheline is present in L3) without
updating the DDR memory. So invalidate after “wait for DMA” in above
sequence would discard latest data and read will cause stale data to be
fetched from DDR. Therefore invalidate after “wait for DMA” is not
always correct on coherent architecture.
Therefore, provide a Kconfig option to disable cache maintenance ops on
coherent architectures. This has added benefit of improving the
performance of DMA transfers as we no longer need to invalidate/flush
individual cache lines(especially for buffer thats several KBs in size).
In order to facilitate use of same Kconfig across different
architecture, I have added the symbol to top level arch/Kconfig file.
Patch currently disables cache maintenance ops for arm64 only.
flush_dcache_all() and invalidate_dcache_all() are exclusively used
during enabling/disabling dcache and hence are not disabled.

commit dffb86e468c8e02ba77283989aefef214d904dc5
Author: Masahiro Yamada <yamada.masahiro@socionext.com>
Date: Wed Aug 12 07:31:54 2015 +0900
of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROL
As we discussed a couple of times, negative CONFIG options make our
life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
and here is another one.
Now, there are three boards enabling OF_CONTROL on SPL:
- socfpga_arria5_defconfig
- socfpga_cyclone5_defconfig
- socfpga_socrates_defconfig
This commit adds CONFIG_SPL_OF_CONTROL for them and deletes
CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert
the logic.

The support for DaVinci DM* SoCs has been dropped a while ago. There's
still a lot of leftover code in mach-davinci though. Entirely remove
certain files and modify the common code to no longer reference
unsupported chips.
Note: all DaVinci platforms supported in u-boot now define SOC_DA8XX
but not all define SOC_DA850 (e.g. omapl138). We can safely remove
all ifdefs for the former, but let's leave the ones for the latter.
