host->mmc, host->mmc->dev and host->mmc->priv must be set
before calling sdhci_setup_cfg() to avoid hang during mmc

23441fbf2b mmc: stm32_sdmmc2: Increase SDMMC_BUSYD0END_TIMEOUT_US
Increase SDMMC_BUSYD0END_TIMEOUT_US from 1s to 2s to
avoid timeout error during blocks erase on some sdcard

Issue seen on Kingston 16GB :
  Device: STM32 SDMMC2
  Manufacturer ID: 27
  OEM: 5048
  Name: SD16G
  Bus Speed: 50000000
  Mode: SD High Speed (50MHz)

  Rd Block Len: 512
  SD version 3.0
  High Capacity: Yes
  Capacity: 14.5 GiB
  Bus Width: 4-bit

Issue reproduced with following command:

STM32MP> mmc erase 0 100000

MMC erase: dev # 0, block # 0, count 1048576 ... mmc erase failed
16384 blocks erased: ERROR

By setting SDMMC_BUSYD0END_TIMEOUT_US at 2 seconds and by adding
time measurement in stm32_sdmmc2_end_cmd() as shown below:

	+start = get_timer(0);
	/* Polling status register */
	ret = readl_poll_timeout(priv->base + SDMMC_STA,
				 status, status & mask,

d7d864017d i2c: mxc_i2c: Remove i2c_idle_bus from probe
i2c_idle_bus is already used in i2c_init_transfer. So before each transfer
if the bus is not ready, the i2c_idle_bus will be used to force idle.
It is unnecessary to call it again in probe.

We found a issue when enabling i2c mux with the mxc_i2c. The mxc_i2c is probed
after mux probing. However, at this moment the mux is still in idle state not
select any port. So if we call i2c_idle_bus in probe, it will fail and cause
mxc_i2c probe failed.

a074667d52 Kconfig: Varios: Fix more SPL, TPL dependencies

This patch is not attempting to be a complete list of items, but
more like low hanging fruit.  In some instances, I wasn't sure
of DM was required, so I simply made them SPL or TPL.

b21dcebfa6 nvme: Fix PRP Offset Invalid
When large writes take place I saw a Samsung EVO 970+ return a status
value of 0x13, PRP Offset Invalid.  I tracked this down to the
improper handling of PRP entries.  The blocks the PRP entries are
placed in cannot cross a page boundary and thus should be allocated
on page boundaries.  This is how the Linux kernel driver works.

With this patch, the PRP pool is allocated on a page boundary and
other than the very first allocation, the pool size is a multiple of
the page size.  Each page can hold (4096 / 8) - 1 entries since the
last entry must point to the next page in the pool.

27e0f3bcf0 arm: ti: Fix regression in distro boot for mmc
When devnum was changed to a local variable in distro_bootcmd we ran
into a problem on TI platforms (confirmed on Beaglebone) as we had been
using 'setenv devnum' there as well and it needs to match the other
usage.

Fixes: 13dd6665ed ("distro: not taint environment variables if possible")

44016bc598 riscv: qemu: Fix kconfig build warning
When 'make qemu-riscv64_defconfig', there is a build warning:

  board/emulation/qemu-riscv/Kconfig:24:
  warning: config symbol defined without type

Fix it by specifying the config symbol type to 'hex'.

8313fcdb4f doc: update QEMU RISC-V documentation
The available defconfigs for RISC-V QEMU have changed. We now have
configurations to compile U-Boot to run in supervisor mode and for
U-Boot SPL. Update the QEMU RISC-V documentation to reflect these
changes.

e456a81935 riscv: qemu: add SPL configuration
Add two new configurations (qemu-riscv{32,64}_spl_defconfig) with SPL
enabled for RISC-V QEMU. QEMU does not require SPL to run U-Boot. The
configurations are meant to help the development of SPL on RISC-V.

The configurations enable RAM as the only SPL boot device. Images must
be loaded at address 0x80200000. In the default boot flow, U-Boot SPL
starts in machine mode, loads the OpenSBI FW_DYNAMIC firmware and U-Boot
proper from the supplied FIT image, and starts OpenSBI. U-Boot proper is
then started in supervisor mode by OpenSBI.

109f82bea9 riscv: set default FIT generator script and build target for SPL builds
Now that we have a generic FIT generator script for RISC-V, set it as
the default. To also build the FIT image by default, set the default
build target to "u-boot.itb" if CONFIG_SPL_LOAD_FIT is enabled.

89fe196c99 riscv: add a generic FIT generator script
Add a generic FIT generator script for RISC-V to generate images
containing U-Boot, OpenSBI FW_DYNAMIC firmware, and optionally one or
more device trees. The location of the OpenSBI firmware binary can be
specified with the OPENSBI environment variable. By default, it is
assumed to be "fw_dynamic.bin", located in the U-Boot top-level. Device
trees are passed as arguments to the generator script. A separate
configuration entry is created for each device tree.

The load addresses of U-Boot and OpenSBI are parsed from the U-Boot
configuration. They can be overwritten with the UBOOT_LOAD_ADDR and
OPENSBI_LOAD_ADDR environment variables.

The script is based on the i.MX (arch/arm/mach-imx/mkimage_fit_atf.sh)
and Allwinner sunxi (board/sunxi/mksunxi_fit_atf.sh) FIT generator
scripts.

c7e1effb96 riscv: support SPL stack and global data relocation
To support relocation of the stack and global data on RISC-V, the
secondary harts must be notified of the change using IPIs. We can reuse
the hart relocation code for this purpose. It uses global data to store
the new stack pointer and global data pointer for the secondary harts.
This means that we cannot update the global data pointer of the main
hart in spl_relocate_stack_gd(), because the secondary harts have not
yet been relocated at this point. It is updated after the secondary
harts have been notified.
