7538ec7d1e ARM: at91: remove no-MMU at91x40 support
As there is currently no-one to take care of this old !MMU target and as its
support in recent kernels is a bit rotten, remove this at91x40 support and the
board file associated with it (at91eb01).
There are modern ARM !MMU in Mainline now so this target is not interesting for
building tests anymore. It would be better to start from these modern ARM !MMU
platforms to reintroduce at91x40 support if needed.

726d32bf79 ARM: at91: SAMA5D4 SoC detection code and low level routines
SoC identification code, kernel uncompress and low level
debugging routines update.
On SAMA5D4, DBGU is at another address AT91_BASE_DBGU2 so another
round of detection is needed. We also had to differentiate with
SAMA5D3 SoC family and rename some variables.

b632a30e8b ARM: remove unused arch_decomp_wdog()
With ARCH_HAS_DECOMP_WDOG removed from arch/arm/boot/compressed/decompress.c,
all the arch_decomp_wdog() definition at platform level is unneeded.
Remmove it.

dca4ba4121 ARM: at91: use __iomem pointers for MMIO
ARM is moving to stricter checks on readl/write functions,
so we need to use the correct types everywhere.

5f29d0a0ee ARM: at91: uncompress: autodetect the uart to use
This will now autodetect the first uart enabled by the bootloader
and will use it for uncompress. This will still assume that the bootloader
configured it (pins and clock).

This also allows to include all soc headers together.

13079a7333 ARM: at91: make DBGU soc independent
we will select now the DBGU used by the soc at Kconfig level

For the DEBUG_LL and early_printk this will allow to select which DBGU to use
this will also allow to select them when multiple SOC are enabled
