Add a basic CPU driver that retrieves information about the microblaze CPU
core. cpu_ops handlers are implemented so that the "cpu" command can work
properly:
U-Boot-mONStR> cpu list
0: cpu@0 MicroBlaze @ 50MHz, Rev: 11.0, FPGA family: zynq7000
U-Boot-mONStR> cpu detail
0: cpu@0 MicroBlaze @ 50MHz, Rev: 11.0, FPGA family: zynq7000
ID = 0, freq = 50 MHz: L1 cache, MMU
Note: cpu_ver_lookup[] and family_string_lookup[] arrays were imported from
linux.

Introduce a minimal cpuinfo structure to hold cache related info. The
instruction/data cache size and cache line size are initialized early in
the boot to default Kconfig values. They will be overwritten with data
from PVR/dtb if the microblaze UCLASS_CPU driver is enabled.
The cpuinfo struct was placed in global_data to allow the microblaze
UCLASS_CPU driver to also run before relocation (initialized global data
should be read-only before relocation).
gd_cpuinfo() helper macro was added to avoid volatile
"-Wdiscarded-qualifiers" warnings when using the pointer directly.

Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing
issues with function pointer arrays which need to be updated manually after
relocation. Building code with -fPIC and linking with -pic will remove this
limitation and there is no longer need to run manual update.
By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC
code will be compiled for full relocation.
The patch does couple of things which are connected to each other.
- Define STATIC_RELA dependency to call relocate-rela to fill sections.
- REMAKE_ELF was already enabled but u-boot file can't be used because
sections are empty. relocate-rela will fill them and output file is
u-boot.elf which should be used.
- Add support for full relocation (u-boot.elf)
- Add support for early relocation when u-boot.bin is loaded to different
address then CONFIG_SYS_TEXT_BASE
- Add rela.dyn and dynsym sections
Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original
size (550kB to 608kB).

Symbol handling depends on compilation flags. Right now manual relocation
is used that's why symbols can be referenced just by name and there is no
need to find them out. But when position independent code (PIC) is used
symbols need to be described differently. That's why having one macro
change is easier than changing the whole code.

Right now U-Boot runs all the time from the same address where it is loaded
but going to full relocation code starting address doesn't need to be fixed
and can be simply discovered from reading PC register. That's why use r20
to get PC address and subtract offset from the beginning to get starting
address.

Enable u-boot.elf recreation from u-boot.bin to prepare for removing manul
relocation. Enable option for big endian configuration but it is not used
too much that's why it is completely untested.
By supporting this system there is a need to define LITTLE/BIG endian
Kconfig options to pass -EL/-EB flags.

CONFIG_SYS_INIT_SP_OFFSET macro place stack to TEXT_BASE - SYS_MALLOC_F_LEN
but there is no reason to do it now because board_init_f_alloc_reserve()
returns exact location where stack should be. That's why stack location is
calculated at run time and there is no need to hardcode it via macro. This
change will help with placing U-Boot to any address.

When U-Boot starts stack protection can be already enabled that's why setup
the lowest possible SLR value which is address 0. And the highest possible
stack in front of U-Boot. That's why you should never load U-Boot to the
beginning of DDR. There must be some space reserved. Code is using this
location for early malloc space, early global data and stack.

The AArch64 TCR_ELx register is a 64-bit register, and many newer
architecture features use bits in the upper half. So far U-Boot was
igorant of those bits, trying to leave them alone.
However, in an effort to set bit 31 to 1, it failed doing so, because
the compiler sign-extended "1 << 31", so that all bits[63:31] got set.
Older ARMv8.0 cores don't define anything dangerous up there, but newer
architecture revisions do, and setting all those bits will end badly:
=================
$ qemu-system-aarch64 -cpu max ....
U-Boot 2022.07-rc1 (May 09 2022 - 15:21:00 +0100)
DRAM: 1.5 GiB
================= (hangs here)
Defining TCR_ELx_RSVD to "1U << 31" avoids the sign-extension, so all
upper bits stay at a safe 0 value. This means no more surprises when
U-Boot runs on a more capable CPU core.

The bulk of it is (finally!) some DT sync from the kernel. We refrained
from syncing one incompatible change, as this would spoil booting Linux
kernels before v5.13 with U-Boot's DT (via UEFI, for instance).
I test booted Linux v5.18 and v5.4 with that new DT on some boards, and
the headless peripherals (MMC, USB, Ethernet) seemed to work.
The rest are fixes:
- silencing missing clock warnings due to the new pinctrl driver
- fixing "UART0 on PortF", allowing UART access through the SD card pins
- add an F1C100s clock driver, to enable MMC support (SPI comes later)
- some cleanups for CONS_INDEX_n in Kconfig
Tested on BananaPi-M1, Pine64-LTS, Pine-H64, X96-Mate (H616) and
OrangePi-Zero.
ARCH_SUNXI selects DM_SERIAL, so the condition can never be satisfied.

When CONFIG_UART0_PORT_F is defined, we try to configure two PortF pins
(usually used for the SD card) as UART0. Some SoCs use the mux value of
3 for this, while others use 4.
The combination of Kconfig symbols we currently use was not quite right:
we mis-configure the A31, A64, H6 and H616.
Going through the list in the pinctrl driver, there are only a few older
SoCs that use a value of 4, so revert the #ifdef clause, and name those
explicitly, instead of the other way around.

The initial U-Boot F1C100s port was based on the mainline kernel DT
files, which were quite basic and were missing the essential MMC and
SPI peripherals. While we could work around this in the SPL by
hardcoding the required information, this left U-Boot proper without SD
card or SPI flash support, so actual loading would require FEL boot.
Now the missing DT bits have been submitted and accepted in the kernel
tree, so lets sync back those files into U-Boot to enable MMC and
SPI, plus benefit from some fixes.
This is a verbatim copy of the .dts and .dtsi file from
linux-sunxi/dt-for-5.19[1], which have been part of linux-next for a
while as well.
