3c1057c548 stm32mp: use device sequence number in boot_instance variable
Use the device sequence number in boot_instance variable
and no more the SDMMC instance provided by ROM code/TF-A.

After this patch we don't need to define the mmc alias in
device tree, for example:
  mmc0 = &sdmmc1;
  mmc1 = &sdmmc2;
  mmc2 = &sdmmc3;
to have a correct mapping between the ROM code boot device =
"${boot_device}${boot_instance}" and the MMC device in U-Boot.

With this patch the 'mmc0' device (used in mmc commands) is
always used when only one instance sdmmc is activated in device
tree, even if it is only the sdmmc2 or sdmmc3.

0f5ca1d1f1 x86: Update the MP constants to avoid conflicts
These constants conflict with error codes returned by the MP
implementation when something is wrong. In particular, mp_first_cpu()
returns MP_SELECT_BSP when running without multiprocessing enabled.
Since this is -2, it is interpreted as an error by callers, which
expect a positive CPU number for the first CPU.

Correct this by using a different range for the pre-defined CPU
numbers, above zero and out of the range of possible CPU values. For
now it is safe to assume there are no more than 64K CPUs.

This fixes the 'mtrr' command when CONFIG_SMP is not enabled.

e2f82f93f8 board: stemmy: Copy atags for booting downstream/vendor kernel
The U-Boot "stemmy" board is mainly intended to simplify booting
mainline Linux on various smartphones from Samsung based on ST-Ericsson
Ux500. While the mainline kernel is working great, there are still some
features missing there. In particular, it is currently not possible to
charge the battery when using the mainline kernel.

This means that it is still necessary to boot the downstream/vendor
kernel from Samsung sometimes to charge the device. That kernel is
ancient, still uses board files + ATAGS instead of device trees and
relies on a strange very long kernel command line hardcoded in the
Samsung bootloader.

Actually, since mainline is booted with device trees there is a very
simple way to make the old downstream kernel work as well: We can
simply take most of the ATAGS passed to U-Boot from the Samsung
bootloader and copy them as-is when booting a kernel without device
tree. That way the long command line and other needed ATAGS are copied
as-is without having to bother with them.

The only exception is the ATAG_INITRD - since the initrd is loaded
by U-Boot, the atag for that should be generated in U-Boot so it points
to the correct address. All other ATAGS are copied as-is and not
generated in U-Boot.

Also use the chance and provide a serial# for U-Boot by parsing the
ATAG_SERIAL that is also passed by the Samsung bootloader.

03585d52fc board: stemmy: Parse atags to get available memory
At the moment the "stemmy" board attempts to detect the RAM size with
a simple memory test (get_ram_size()). Unfortunately, this does not work
correctly for devices with 768 MiB RAM (e.g. Samsung Galaxy Ace 2
(GT-I8160), "codina"). Reading/writing memory after the 768 MiB RAM
succeeds but actually overwrites some earlier parts of the memory.

For U-Boot this does not result in any major problems, but on Linux
this will eventually lead to strange crashes because of the memory
corruption.

Since the "stemmy" U-Boot port is designed to be chainloaded from
the original Samsung bootloader, the most reliable way to get the
available amount of RAM is to look at the ATAGS passed by the Samsung
bootloader. Fortunately, the header used to generate ATAGS in U-Boot
(asm/setup.h) can also be easily used to parse them.

Also clarify and simplify stemmy.h a bit to make it more clear where
some of the magic values in there are actually coming from.

548b89f8ad arm: mach-snapdragon: pinctrl: Place pin_name in .data section
According to arch/arm/lib/crt0_64.S, the BSS section is "UNAVAILABLE"
and uninitialized before relocation. Also, it overlaps with the
appended DTB before relocation, so writing data into a variable
in the BSS section might corrupt the appended DTB.

Unfortunately, pinctrl-apq8016.c and pinctrl-apq8096.c do place the
"pin_name" variable in the BSS section (since it's uninitialized).
It's also used before relocation, when setting up the pinctrl for
the serial driver.

On DB410c this causes "GPIO_5" to be written into some part of an
appended DTB, e.g.:

80111820: edfe0dd0 9f100000 38000000 c00e0000    ...........8....
80111830: 28000000 11000000 10000000 00000000    ...(............
80111840: 4f495047 8800355f 00000000 00000000    GPIO_5..........
80111850: 00000000 00000000 01000000 00000000    ................
80111860: 03000000 04000000 00000000 02000000    ................
80111870: 03000000 04000000 0f000000 02000000    ................
80111880: 03000000 2d000000 1b000000 6c617551    .......-....Qual
80111890: 6d6d6f63 63655420 6c6f6e68 6569676f    comm Technologie

Depending on the part of the DTB that is corrupted this might not
cause any problems, but it can also result in strange reboots
without any serial output.

Fortunately, in practice this does not cause issues on DB410c yet
because board_fdt_blob_setup() in dragonboard410c.c currently
overrides the appended DTB with the one passed by the previous
bootloader (LK) (which does not get corrupted).

DB820c does not have board_fdt_blob_setup() so I would expect it to
be affected by this problem. Perhaps everyone was just fortunate to
not compile an U-Boot configuration where the pin_name corrupts an
important part of the DTB.

Make sure "pin_name" is explicitly placed in the .data section
instead of .bss to fix this.

a5ee05cf71 ARM: imx: Pick correct eMMC boot partition from ROM log
In case the iMX8M boot from eMMC boot partition and the primary image
is corrupted, the BootROM is capable of starting a secondary image in
the other eMMC boot partition as a fallback.

However, the BootROM leaves the eMMC BOOT_PARTITION_ENABLE setting as
it was, i.e. pointing to the boot partition containing the corrupted
image, and the BootROM does not provide any indication that this sort
of fallback occured.

According to AN12853 i.MX ROMs Log Events, Rev. 0, May 2020, it is
possible to determine whether fallback event occurred by parsing the
ROM event log. In case ROM event ID 0x51 is present, fallback event
did occur.

This patch implements ROM event log parsing and search for event ID
0x51 for all iMX8M SoCs, and based on that corrects the eMMC boot
partition selection. This way, the SPL loads the remaining boot
components from the same eMMC boot partition from which it was
started, even in case of the fallback.

1feac813fe board: phytec: phycore_imx8mp: Change debug UART
With the first redesign the debug UART had changed from
UART2 to UART1.
As the first hardware revision is considered as alpha and
will not be supported in future. The old setup will not
be preserved.

c1f6fd2bb7 pci: imx: use reset-gpios if defined by device-tree
If reset-gpio is defined by device-tree use that if
CONFIG_PCIE_IMX_PERST_GPIO is not defined.

Note that after this the following boards which define
CONFIG_PCIE_IMX_PERST_GPIO in their board header file as well as their
device-tree should be able to remove CONFIG_PCIE_IMX_PERST_GPIO without
consequence:
 - mx6sabresd
 - mx6sxsabresd
 - novena
 - tbs2910
 - vining_2000

Note that the ge_bx50v3 board uses CONFIG_PCIE_IMX_PERST_GPIO and does
not have reset-gpios defined it it's pcie node in the dt thus removing
CONFIG_PCIE_IMX_PERST_GPIO globally can't be done until that board adds
reset-gpios.

e27bddff4b imx8m: Restrict usable memory to space below 4G boundary
Some IPs have their accessible address space restricted by the
interconnect. Let's make sure U-Boot only ever uses the space below
the 4G address boundary (which is 3GiB big), even when the effective
available memory is bigger.

We implement board_get_usable_ram_top() for all i.MX8M SoCs, as the
whole family is affected by this.

490101a5e5 Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
Aside from the usual fixes and updates one visible change is the
MMC update, which fixes some lingering bugs and gives a decent speed
increase on some boards (9->19 MB/s on H6, 21->43 MB/s on A64 eMMC).
I am keeping an watchful eye on bug reports here, to spot any correctness
regressions.
Another change is finally the enablement of the first USB host port on
many boards without micro-USB (data) sockets, like the Pine64 family.
That doubles the number of usable USB ports from 1 to 2 on those boards.

Some smaller fixes, 4GB DRAM support (on the H616) and a new board (ZeroPi)
conclude this first round of changes.

Compile-tested for all 157 sunxi boards, boot-tested on Pine H64,
Pine64-LTS, OrangePi Zero 2 and BananaPi M2 Berry.

Summary:
- DT update for H3/H5/H6
- Enable first USB port on boards without micro-USB
- ZeroPi board support
- 4GB DRAM support for H616 boards
- MMC fixes and speed improvement
- some fixes

9faae5457f mmc: sunxi: Increase MMIO FIFO read performance
To avoid the complexity of DMA operations (with chained descriptors), we
use repeated MMIO reads and writes to the SD_FIFO_REG, which allows us
to drain or fill the MMC data buffer FIFO very easily.

However those MMIO accesses are somewhat costly, so this limits our MMC
performance, to between 17 and 22 MB/s, but down to 9.5 MB/s on the H6
(partly due to the lower AHB1 frequency).

As it turns out we read the FIFO status register after *every* word we
read or write, which effectively doubles the number of MMIO accesses,
thus effectively more than halving our performance.

To avoid this overhead, we can make use of the FIFO level bits, which are
in the very same FIFO status registers.
So for a read request, we now can collect as many words as the FIFO
level originally indicated, and only then need to update the status
register.

We don't know for sure the size of the FIFO (and it seems to differ
across SoCs anyway), so writing is more fragile, which is why we still
use the old method for that. If we find a minimum FIFO size available on
all SoCs, we could use that, in a later optimisation.

This patch increases the eMMC read speed on a Pine64-LTS from about
22MB/s to 44 MB/s. SD card reads don't gain that much, but with 23 MB/s
we now reach the practical limit for 3.3V SD cards.
On the H6 we double our transfer speed, from 9.5 MB/s to 19.7 MB/s.

937ee31e32 mmc: sunxi: Fix MMC clock parent selection
Most Allwinner SoCs which use the so called "new timing mode" in their
MMC controllers actually use the double-rate PLL6/PERIPH0 clock as their
parent input clock. This is interestingly enough compensated by a hidden
"by 2" post-divider in the mod clock, so the divider and actual output
rate stay the same.

Even though for the H6 and H616 (but only for them!) we use the doubled
input clock for the divider computation, we never accounted for the
implicit post-divider, so the clock was only half the speed on those SoCs.
This didn't really matter so far, as our slow MMIO routine limits the
transfer speed anyway, but we will fix this soon.

Clean up the code around that selection, to always use the normal PLL6
(PERIPH0(1x)) clock as an input. As the rate and divider are the same,
that makes no difference.
Explain the hardware differences in a comment.
