c2a2123e33 cmd: cache: Fix non-cached memory cachability
If dcache is switched OFF to ON state and if non-cached memory is
used, this non-cached memory must be re-declared as uncached to mmu
each time dcache is set ON.

Introduce noncached_set_region() to set this non-cached region's mmu
settings. Let architecture override it by defining it as a weak
function.

For ARM architecture, noncached_set_region() defines all noncached
region as non-cacheable.

Issue found on STM32MP1 platform using dwc_eth_qos ethernet driver,
when going from dcache OFF to dcache ON state, ethernet driver issued
TX timeout errors when performing dhcp or ping.

It can be reproduced with the following sequence:

dhcp
while true ; do
  ping 192.168.1.300 ;
  dcache off ;
  ping 192.168.1.300 ;
  dcache on ;
done

56e403d95f arm: juno: enable USB
The Juno board features a standard compliant EHCI/OHCI USB host
controller pair, which we can just enable.
The platform data is taken from the device tree.

This allows to use USB mass storage (the only storage on a Juno r0)
for loading.

At least on my board USB seems a bit flaky, I need two "usb reset"
sequences after the "usb start" to detect an USB hard drive.

b3270e9138 arm: juno: Enable OF_CONTROL
The Arm Juno board was still somewhat stuck in "hardcoded land", even
though there are stable DTs around, and one happens to actually be on
the memory mapped NOR flash.

Enable the configuration options to let the board use OF_CONTROL, and
add a routine to find the address of the DTB partition in NOR
flash, to use that for U-Boot's own purposes.
This can also passed on via $fdtcontroladdr to any kernel or EFI
application, removing the need to actually load a device tree.

Since the existing "afs" command and its flash routines require
flash_init() to be called before being usable, and this is done much
later in the boot process, we introduce a stripped-down partition finder
routine in vexpress64.c, to scan the NOR flash partitions for the
DT partition. This location is then used for U-Boot to find and probe
devices.

The name of the partition can be configured, if needed, but defaults
to "board.dtb", which is used by Linaro's firmware image provided.

a15d0aa680 imx: spl: return boot mode for asked MMC device in spl_mmc_boot_mode()
Boards may extend or re-define the boot list in their board_boot_order()
function by modifying spl_boot_list. E.g. a board might boot SPL from a
slow SPI NOR flash and then load the U-Boot from an eMMC or SD-card.
Or it might use additional MMC boot device in spl_boot_list for cases
when the image in SPI NOR flash is not found, so it could fall back to
eMMC, SD-card or another boot device.

Getting the MMC boot mode in spl_mmc will fail when we are trying to
boot from an MMC device in the spl_boot_list and the original board
boot mode (as returned by spl_boot_device()) is not an MMC boot mode.
Fix it by checking the asked MMC boot device from the spl_mmc_boot_mode()
argument.

54be09cd8f arm: caches: manage phys_addr_t overflow in mmu_set_region_dcache_behaviour
Solved the overflow on phys_addr_t type for start + size in
mmu_set_region_dcache_behaviour() function.

This overflow is avoided by dividing start and end by 2 before addition,
and we only expecting that start and size are even.

This patch doesn't change the current function behavior if the
parameters (start or size) are not aligned on MMU_SECTION_SIZE.

For example, this overflow occurs on ARM32 with:
start = 0xC0000000 and size = 0x40000000
then start + size = 0x100000000 and end = 0x0.

For information the function behavior change with risk of regression,
if we just shift start and size before the addition.
Example with 2MB section size:
  MMU_SECTION_SIZE 0x200000 and MMU_SECTION_SHIFT = 21
  with start = 0x1000000, size = 0x1000000,
  - with the proposed patch, start = 0 and end = 0x1 as previously
  - with the more simple patch:
    end = (start >> MMU_SECTION_SHIFT) + (size >> MMU_SECTION_SHIFT)
    the value of end change:
    start >> 21 = 0, size >> 21 = 0 and end = 0x0 !!!

f24dea4e1b ARM: imx8m: Fix reset in SPL on NXP iMX8MP EVK
Board files should not re-implement do_reset() to work around this
function not being defined in for specific configurations. Rather,
the fix is to compile in drivers which implement this properly.
This patch enables sysreset and watchdog drivers in SPL and ties
them together to implement the same as the do_reset() hack in the
board file, except correctly in the DM/DT framework.

c5635a032a ARM: imx8m: Don't use the addr parameter of reset_cpu()
imx8m has the only implementation of reset_cpu() which does not ignore
the addr parameter and instead gives it some meaning as the base address
of watchdog registers.  This breaks convention with the rest of U-Boot
where the parameter is ignored and callers are passing in 0.
