f002b3fa8d board/lx2160a: Fix MC firmware loading for SD boot
During boot, u-boot reads MC, DPL, DPC firmware from SD card
and copies to DDR. Update DDR addresses to which these firmwares
are copied as per memory map of these firmwares on SD-card
so that isolation between the regions of various firmwares
is maintained to avoid geting overwritten.

29009a507c mmc: Kconfig: Add FSL_ESDHC_USE_PERIPHERAL_CLK option
NXP fsl_esdhc controller supports two reference clocks:
platform clock and peripheral clock
Peripheral clock can provide higher clock frequency
which is required to be used for tuning of SD UHS mode
and eMMC HS200/HS400 modes.

Peripheral clock is enabled by default by defining config
option FSL_ESDHC_USE_PERIPHERAL_CLK if eMMC HS200/HS400 modes
are supported.

b35b807682 usb: xhci-dwc3: Add support for dis_u2_susphy_quirk
This quirk is necessary for the Amlogic GXL SoCs otherwise the
Port 2 PHY doesn't get out of suspend and U-Boot resets the board after:

XHCI timeout on event type 33... cannot recover.
BUG: failure at drivers/usb/host/xhci-ring.c:474/xhci_wait_for_event()!
BUG!

This quirk is also handled in the dwc3 core code, but until the
xhci-dwc3 driver uses the dwc3 core, the quirk must be handled here
to fix USB support on the Amlogic libretech-cc and libretech-ac board
when a device is only plugged in the OTG port.

This defines a minimum defconfig for each of the two Raspberry Pi 4
variants. One notable difference is that we don't have a embedded dt for
this board given that the fw supplies us with one which we can reuse.
Furthermore, the ram size is not queryable through mbox interface as the
maximum reported size is 1G. The fw patches the dt with the right
memory configuration and uboot uses it as it is. We avoid u-boot
touching this configuration by making sure CONFIG_ARCH_FIXUP_FDT_MEMORY

Some cards require wait times of up to ~56 ms to perform
the command 'saveenv' on an EXT4 partition.

Re-implement the loop exit condition to use get_timer() which allows
to specify the wait time in more reliable manner. Set the maximum wait
time to the originally intended 1 second.

49822442ed ARM: bcm283x mbox: Fix send status register
Before we can send a message to the mailbox we have to check that there
is space to do so. Therefore we poll the status register. But up to now
the wrong status register, the one of mailbox 0, was checked. Fix this
by polling the status regiser of mailbox 1.

cd45d6f395 mmc: sdhci: Add support for dt caps & caps mask
The sdhci capabilities registers can be incorrect. The
sdhci-caps-mask and sdhci-caps dt properties specify which bits of
the registers are incorrect and what their values should be. This
patch makes the sdhci driver use those properties to correct the caps.
Also use "dev_read_u64_default" instead of "dev_read_u32_array" for
caps mask.
