env: sunxi: Define location in SPI flash
To allow loading and storing the environment from SPI flash, adjust the
raw offset variables for Allwinner boards to make sense there.
U-Boot (including SPL and other blobs) is loaded from the beginning of
SPI flash, so move the environment location as far back as possible, to
not create unnecessary limits. As those offsets are shared with (now
mostly unused) raw MMC environment, we should respect the common one
megabyte limit, which also makes sense on SPI flash.
So limit the environment for those raw locations to 64KB, and place it
just below 1MB (@960KB).
Those values are currently unused, unless someone forcibly enables the
raw MMC environment. In this case it would break as of now, as the
current offset of 544KB is far too low for the current (arm64) U-Boot
proper.

sunxi: Kconfig: Fix up SPI configuration
Commit 7945caf22c44 ("arm: sunxi: Enable SPI/SPI-FLASH support for A64")
selected CONFIG_SPI by default on all Allwinner A64 boards, even though
only 4 out of the 14 A64 boards have a SPI flash chip. All other SoCs
had to manually select DM_SPI and friends, even though they are a
platform property (the sunxi SPI driver is DM_SPI only).
Clean this up to allow easy selection of SPI flash support in U-Boot
proper, by selecting DM_SPI and DM_SPI_FLASH *if* CONFIG_SPI is
selected, for *all* Allwinner SoCs. This simplifies the defconfig for
two Libretech boards already.
Also remove the forced CONFIG_SPI from the A64 Kconfig, instead let the
four boards which allow SPI booting select this explicitly.
Any board wishing to support SPI flash in U-Boot proper now just defines
CONFIG_SPI and CONFIG_SPI_FLASH_<vendor> in its defconfig, Kconfig takes

actually doing, I haven't studied the DDR training algorithm and
I suspect that no one will be able to explain it to U-Boot contributors,
so we are left with this blind poking in the code with testing whether
it works on several boards and hoping it doesn't break anything for
anyone :-(.

arm: mvebu: a37xx: Map CCI-400 and AP BootROM address space
In function build_mem_map() prepare also mapping for CCI-400 and
BootROM windows.
BootROM window is 1 MB long and by default starts at address 0xfff00000.
A53 AP BootROM is 16 kB long and repeats in this BootROM window 64 times.
RVBAR_EL3 register is set to value 0xffff0000, so by default A53 AP BootROM
is accessed via range 0xffff0000-0xffff3fff.
CCI-400 window when new TF-A version is used, starts at address 0xfe000000
and when old TF-A version is used, starts at address 0xd8000000.
Physical addresses are read directly from mvebu registers, so if TF-A
remaps it in future (again) then it would not cause any issue for U-Boot.

arm: mvebu: a37xx: Fix calling build_mem_map()
Function build_mem_map() modifies global variable mem_map. This variable is
used by the get_page_table_size() function which is called by function
arm_reserve_mmu() (as aliased macro PGTABLE_SIZE). Function
arm_reserve_mmu() is called earlier than enable_caches() which calls
build_mem_map(). So arm_reserve_mmu() does not calculate reserved memory
correctly.
Fix this issue by calling build_mem_map() from a3700_dram_init() which is
called before arm_reserve_mmu().

arm: a37xx: pci: Do not try to access other buses when link is down
If a PIO request is executed while link-down, the whole controller gets
stuck in a non-functional state, and even after link comes up again, PIO
requests won't work anymore, and a reset of the whole PCIe controller is
needed. Therefore we need to prevent sending PIO requests while the link
is down.
