b411ba9210 xen: Limit execution to EL1 only
Xen core_init() is calling HVC which should be called from EL1 level that's
why do Xen initialization only when U-Boot runs in EL1.

44cd761ad6 xen: Fix Kconfig dependencies
XEN config can be enabled by other platforms (even it doesn't need to make
sense) that's why fix dependencies. XEN (xenbus.c) requires sscanf (also
pvblock needs it). And PVBLOCK is inside drivers/xen folder which requires
XEN to be enabled.

in spi_mem_dtr_supports_op we have a check for allowing only even number
of bytes to be r/w. Odd bytes writing can be a concern while writing
data to a flash for example because 8 DTR mode doesn't support it.
However, reading ODD Bytes even  though may not be physically possible
we can still allow for it because it will not have serious implications
on any critical registers being overwritten since they are just reads.

b91a0822d7 mtd: spi-nor: Add CHIP_ERASE optimization
Add support for CHIP_ERASE opcode 0xc7 . This is useful in case the
entire SPI NOR is supposed to be erase at once, as is it considerably
faster than 4k sector erase and even slightly faster than 64k block
erase. The spi_nor_erase_chip() implementation is adapted from Linux
6.1.y as of commit 7d54cb2c26dad ("Linux 6.1.14") . The chip erase is
only used in case the entire MTD device is being erased, and the chip
does support this functionality.

Timing figures from W25Q128JW:
16 MiB erase using 4kiB sector erase opcode 0x20 ... 107.5s
16 MiB erase using 64kiB block erase opcode 0xd8 ... 39.1s
16 MiB erase using chip erase opcode 0xc7 .......... 38.7s

b0a2fe148a virtio: Use bounce buffers when VIRTIO_F_IOMMU_PLATFORM is set

770e77051e mtd: rawnand: nand_base: Handle algorithm selection
For BRCMNAND with 1-bit BCH ECC (BCH-1) such as used on the
D-Link DIR-885L and DIR-890L routers, we need to explicitly
select the ECC like this in the device tree:

  nand-ecc-algo = "bch";
  nand-ecc-strength = <1>;
  nand-ecc-step-size = <512>;

This is handled by the Linux kernel but U-Boot core does
not respect this. Fix it up by parsing the algorithm and
preserve the behaviour using this property to select
software BCH as far as possible.

a3cab289f6 mmc: rockchip_sdhci: Add support for RK3588
Add support for RK3588 to the rockchip sdhci driver.

Use driver data to handle differences between RK3568 and RK3588:

- Set "Receive original clock source is auto gating" for RK3588.
- Set "Receive clock source is no-inverted" only on RK3568 and "Transmit
  clock source is invertion of original clock input" for RK3588.
- Use different txclk_tapnum for HS400 modes on RK3588.
- Configure the CMDOUT reg for HS400 modes for RK3588.

This is based on the mainline linux and vendor kernel driver and have
successfully been tested with rock5b-rk3588_defconfig and

  CONFIG_MMC_HS200_SUPPORT=y
  CONFIG_MMC_HS400_SUPPORT=y
  CONFIG_MMC_HS400_ES_SUPPORT=y
  CONFIG_MMC_SPEED_MODE_SET=y

using the following command to switch mode and then read 512 MiB of data
from eMMC into memory,

  => mmc dev 0 0 <mode> && mmc info && mmc read 10000000 2000 10000

for each of the modes below.

  0 = MMC legacy
  1 = MMC High Speed (26MHz)
  3 = MMC High Speed (52MHz)
  4 = MMC DDR52 (52MHz)
  10 = HS200 (200MHz)
  11 = HS400 (200MHz)
  12 = HS400ES (200MHz)

Adjust tap number for transmit clock, tap number and delay number for

8874c417ab mmc: rockchip_sdhci: Rearrange and simplify used regs and flags
This rearrange and remove duplicate defines to make the code cleaner.

There is no need to read vendor area1 and use an offset each time, it is
easier and clearer to just use the reg offset defined in TRM, same as
the other vendor regs.

This also removes use of the misspelled const for the RK3588 CMDOUT reg,
it will be re-added when support for RK3588 is introduced.

b8c394b726 mmc: rockchip_sdhci: Fix use of device private data
The device private data is misused in rockchip_sdhci_of_to_plat and
rockchip_sdhci_execute_tuning.

In these functions dev_get_priv is assigned to struct sdhci_host:

  struct sdhci_host *host = dev_get_priv(dev);

Instead, the sdhci host should refer to host in struct rockchip_sdhc:

  struct rockchip_sdhc *priv = dev_get_priv(dev);
  struct sdhci_host *host = &priv->host;

Because host is the first member in struct rockchip_sdhc this is not a
real problem, lets fix it anyway and also use priv name consistently.
