defd62ca13 arm: dts: k3-am64-main: Update the location of ATF in SRAM and increase its max size
Due to a limitation for USB DFU boot mode, SPL load address has to be less
than  or equal to 0x70001000. So, load address of SPL and ATF have been
moved to 0x70000000 and 0x701a0000 respectively.

Also, the maximum size of ATF has been increased to 0x1c000 [1].

Therefore, update ATF's location and maximum size accordingly in the device
tree file.

26f32c32b2 configs: am64x_evm_*_defconfig: Rearrange the components in SRAM to satisfy the limitations for USB DFU boot mode
For USB DFU boot mode there is a limitation on the load address of boot
images that they have to be less than 0x70001000. Therefore, move the
SPL_TEXT_BASE address to 0x70000000.

Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at
0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move
the location of ATF to a latter location in SRAM, past the SPL image. Also
rearrange the EEPROM and BSS data on top of ATF.

Given below is the placement of various data sections in SRAM

669a03e0ff arm: mach-k3: am642_init: Do USB fixups to facilitate host and device boot modes
U-Boot either supports USB host or device mode for a node at a time in the
device tree nodes. To support both host and dfu bootmodes, dr_mode is set
to "peripheral" by default and then fixed based on the mode selected by
the boot mode config dip switches on the board.

This needs to happen before the cdns3 generic layer binds the usb device
to a host or a device driver. Therefore, use fdtdec_setup_board()
implementation to fixup the device tree property.

6ac4d44806 arm: imx: imx8mm: correct unrecognized fracpll frequency
Frequency requested by ddrphy_init_set_dfi_clk from fracpll uses MHZ()
macro, which expands the value provided to the Hz range without taking into
account the precise Hz setting. This causes the frequency of 266 MHz not ot
be found in the imx8mm_fracpll_tbl, since it is entered there with a
precise Hz value. This in turn causes the boot hang in SPL, as proper DDR
fracpll frequency cannot be determined.

Correct the value in imx8mm_fracpll_tbl to match the one expanded by
MHZ(266) macro, rounding it down to MHz range only.

PCI devices on init such as the e1000 that is present on the GW552x.

Convert board_pci_fixup to use dm callback and remove pcidisable env
variable which is not supported for DM_PCI and thus leave PCI always
enabled during init.

d9a7f1a913 arm: imx: imx8mm: clock: make debug output more descriptive
Clock initialization functionality has ambitious debug messages, which are
printed out when failures are triggered during execution:
- Separate frequency table lookup functions have the the same output that
  makes it impossible to understand which function failed and produced the
  output
- PLL decoding routine has a generic debug statement printed, which does
  not state the actual value failed to be found

Extend the output for both cases with prefixing table lookup functions
output with function name, and report the failed value in PLL decoding
routine.

ade4e0428f stm32mp: don't map the reserved region with no-map property
No more map the reserved region with "no-map" property by marking
the corresponding TLB entries with invalid entry (=0) to avoid
speculative access.

The device tree parsing done in lmb_init_and_reserve() takes a
long time when it is executed without data cache, so it is called in
enable_caches() before to disable it.

This patch fixes an issue where predictive read access on secure DDR
OP-TEE reserved area are caught by firewall.

Add 8M for the U-Boot reserved memory (display, fdt, gd, ...)

Without this patch the device tree, located before the MALLOC area
is not tagged cacheable just after relocation, before mmu reconfiguration.

This patch reduces the duration for device tree parsing in
lmb_init_and_reserve.

55661ee0e3 Revert "sama5d3: Fix Galois Field Table offsets"
This reverts commit 786f888b74.

Looks like the datasheet at
https://ww1.microchip.com/downloads/en/DeviceDoc/SAMA5D3-Series-Data-sheet-DS60001609b.pdf
is wrong, and the testing was poorly done, because the PMECC did not raise
any error, but also didn't correct any bitflips. Restoring the offsets
as they were before, makes the PMECC on sama5d3x capable of correcting
bitflips.

079b35a261 arm: a37xx: pci: Increase PCIe MEM size from 16 MiB to 127 MiB
For some configurations with more PCIe cards and PCIe bridges, 16 MiB of
PCIe MEM space may not be enough. Since TF-A already allocates a 128 MiB
CPU window for PCIe, and since IO port space is only 64 KiB in total,
use all the remaining space (64 + 32 + 16 + 8 + 4 + 2 + 1 = 127 MiB) for
PCIe MEM.

4a82fca8e3 arm: a37xx: pci: Fix a3700_fdt_fix_pcie_regions() function
Current version of this function uses a lot of incorrect assumptions about
the `ranges` DT property:

 * parent(#address-cells) == 2
 * #size-cells == 2
 * number of entries == 2
 * address size of first entry == 0x1000000
 * second child address entry == base + 0x1000000

Trying to increase PCIe MEM space to more than 16 MiB leads to an overlap
with PCIe IO space, and trying to define additional MEM space (as a third
entry in the `ranges` DT property) causes U-Boot to crash when booting the
kernel.

  ## Flattened Device Tree blob at 04f00000
     Booting using the fdt blob at 0x4f00000
     Loading Device Tree to 000000001fb01000, end 000000001fb08f12 ... OK
  ERROR: board-specific fdt fixup failed: <unknown error>
   - must RESET the board to recover.

Fix a3700_fdt_fix_pcie_regions() to properly parse and update all addresses
in the `ranges` property according to
https://elinux.org/Device_Tree_Usage#PCI_Address_Translation

Now it is possible to increase PCIe MEM space from 16 MiB to maximal value
of 127 MiB.

6785434709 sunxi: Bring back SD card as MMC device 0
Commit 2243d19e56 ("mmc: mmc-uclass: Use dev_seq() to read aliases
node's index") now actually enforces U-Boot's device enumeration policy,
where explicitly named devices come first, then any other non-named
devices follow, without filling gaps.

For quite a while we have had an "mmc1 = &mmc2;" alias in our
sunxi-u-boot.dtsi, which now leads to the problem that the SD card
(which was always mmc device 0) now gets to be number 2.
This breaks quite some boot scripts, including our own distro boot
commands, and some other features looking at $mmc_bootdev, also
fastboot.

Just add an explicit mmc0 alias in the very same file to fix this and
restore the old behaviour.
