Today the bootcount is not managed by the Linux kernel for STM32MP15 as
we don't have driver to update the used backup register in TAMP and the
recovery command still executes the normal bootcmd with
'altbootcmd=run bootcmd'.
So the bootcount feature is never used, the config CONFIG_BOOTCOUNT_LIMIT
and the associated environment variable 'altbootcmd' can be removed to
reduce the U-Boot size.
Each boards can re-enable this feature later in their defconfig, if it is
needed, with the expected backend, for example CONFIG_BOOTCOUNT_GENERIC
or CONFIG_BOOTCOUNT_ENV.

ARM: dts: stm32: Add DFU support for DHCOR recovery
This patch configures U-Boot SPL for DHCOR SoM to permit DFU upload of
SPL and subsequent u-boot.itb for recovery or commissioning purposes.
To start U-Boot on DHCOR based board, e.g. Avenger96, proceed as follows:
- Install dfu-util on the host PC (in debian this is package 'dfu-util')
- Power off the Avenger96 board.
- Connect both USB-serial console and USB-OTG microB ports to host PC.
- Switch Avenger96 to USB boot mode -- BOOT0..2 switches all set to 0.
- Power on the Avenger96 board.
- Verify using '$ dmesg' that a new device has been detected as follows:
New USB device found, idVendor=0483, idProduct=df11, bcdDevice= 2.00
New USB device strings: Mfr=1, Product=2, SerialNumber=3
Product: DFU in HS Mode @Device ID /0x500, @Revision ID /0x0000
Manufacturer: STMicroelectronics
- Upload U-Boot SPL:
$ dfu-util -a 1 -D u-boot-spl.stm32
- Upload U-Boot proper:
$ dfu-util -a 0 -D u-boot.itb
- At this point, SPL will wait for user to press "Ctrl-C" on serial
console. When ready to interact with U-Boot, press Ctrl-C to start
the bootloader.

Fixup device tree blob to disable SATA node if mSATA card is not

fs/btrfs: fix a bug that U-boot fs btrfs implementation doesn't handle NO_HOLE feature correctly

md5 for 01000000 ... 01002fff ==> 855ffdbe4d0ccc5acab92e1b5330e4c1
The md5sum doesn't match at all.
[CAUSE]
In U-boot btrfs implementation, the function btrfs_read_file() has the
following iteration for file extent iteration:
/* Read the aligned part */
while (cur < aligned_end) {
ret = lookup_data_extent(root, &path, ino, cur, &next_offset);
if (ret < 0)
goto out;
if (ret > 0) {
/* No next, direct exit */
if (!next_offset) {
ret = 0;
goto out;
}
}
/* Read file extent */
But for NO_HOLES features, hole extents will not have any extent item
for it.
Thus if @cur is at a hole, lookup_data_extent() will just return >0, and
update @next_offset.
But we still believe there is some data to read for @cur for ret > 0
case, causing we read extent data from the next file extent.
This means, what we do for above NO_HOLES btrfs is:
- Read 4K data from disk to file offset [0, 4K)
So far the data is still correct
- Read 4K data from disk to file offset [4K, 8K)
We didn't skip the 4K hole, but read the data at file offset [8K, 12K)
into file offset [4K, 8K).
This causes the checksum mismatch.
[FIX]
Add extra check to skip to the next non-hole range after
lookup_data_extent().

ARM: dts: at91: sama7g5ek: move eeproms to flexcom8
The rev4 of the board sama7g5ek has the eeproms on flexcom8 instead of
flexcom1.
Initialize flexcom8 with required pincontrol and move the eeproms accordingly.

ARM: dts: at91: sama7g5: add flx8 and required nodes
Add Flexcom8 node with required referenced nodes as phandles.
Since Flexcom8 is present in Linux, take the node exactly as-is from Linux.
Some nodes are referenced in Linux as phandles, the dma and the gic.
Add them as well to the file, even if they are unused by Uboot.
This is a step towards having the U-boot DT equivalent with the DT in Linux.

For configurations with gmii2rgmii and external phy the DT nodes link
should be gem->gmii2rgmii->phy. But due to limitation in Linux driver
the DT is mentioned as gem->phy and gmii2rgmii->phy as shown in below DT.
Since same DT is used in Linux and U-Boot we need to workaround this
issue by using the gmii2rgmii node which points to phy and we should
ignore the gem pointing to phy directly.
Do this workaround by updating priv->phydev->node value with
priv->phy_of_node only if it is not valid node.
