b6055945d6 ARM: dts: stm32: Adjust PLL4 settings on AV96 again
PLL4Q is supplying both FDCAN and LTDC. In case HDMI is in use, the
50 MHz generated from PLL4Q cannot be divided well enough to produce
accurate clock for HDMI pixel clock. Adjust it to generate 74.25 MHz
instead. The PLL4P/PLL4R are generating 99 MHz instead of 100 MHz,
which is in tolerance for the SDMMC.

ac458dc823 bcmgenet: fix DMA buffer management
This commit fixes a serious issue occurring when several network
commands are run on a raspberry pi 4 board: for instance a "dhcp"
command and then one or several "tftp" commands. In this case,
packet recv callbacks were called several times on the same packets,
and send function was failing most of the time.

note: if the boot procedure is made of a single network
command, the issue is not visible.

The issue is related to management of the packet ring buffers
(producer / consumer) and DMA.
Each time a packet is received, the ethernet device stores it
in the buffer and increments an index called RDMA_PROD_INDEX.
Each time the driver outputs a received packet, it increments
another index called RDMA_CONS_INDEX.

Between each pair of network commands, as part of the driver
'start' function, previous code tried to reset both RDMA_CONS_INDEX
and RDMA_PROD_INDEX to 0. But RDMA_PROD_INDEX cannot be written from
driver side, thus its value was actually not updated, and only
RDMA_CONS_INDEX was reset to 0. This was resulting in a major
synchronization issue between the driver and the device. Most
visible behavior was that the driver seemed to receive again the
packets from the previous commands (e.g. DHCP response packets
"received" again when performing the first TFTP command).

This fix consists in setting RDMA_CONS_INDEX to the same
value as RDMA_PROD_INDEX, when resetting the driver.

The same kind of fix was needed on the TX side, and a few variables
had to be reset accordingly (c_index, tx_index, rx_index).

The rx_index and tx_index have only 256 entries so the bottom 8 bits
must be masked off.

92bc179c5f fs: btrfs: Use btrfs_readlink() to implement __btrfs_readlink()
The existing __btrfs_readlink() can be easily re-implemented using the
extent buffer based btrfs_readlink().

This is the first step to re-implement U-Boot's btrfs code.

cafffc50ad fs: btrfs: Rename path resolve related functions to avoid name conflicts
Since the old code is using __btrfs_path/__btrfs_root which is different
from the regular extent buffer based one, we add "__" prefix for the old
implementation to avoid name conflicts for the incoming crossport.

f06bfcf54d fs: btrfs: Crossport open_ctree_fs_info() from btrfs-progs
open_ctree_fs_info() is the main entry point to open btrfs.

This version is a simplfied version of __open_ctree_fd() of btrfs-progs,
the main differences are:
- Parameters on how to specify a block device
  Instead of @fd and @path, U-Boot uses blk_desc and disk_partition_t.

- Remove open_ctree flags
  There won't be multiple open ctree modes in U-Boot.

Otherwise functions structures are all kept the same.

With open_ctree_fs_info() implemented, also introduce the global
current_fs_info pointer to show the current opened btrfs.

57f24f1073 fs: btrfs: Crossport btrfs_read_sys_array() and btrfs_read_chunk_tree()
These two functions play a big role in btrfs bootstrap.

The following function is removed:
- Seed device support

Although in theory we can still support multiple devices, we don't have
a facility in U-Boot to do device scan without opening them.

29c26ae8bc fs: btrfs: Crossport btrfs_search_slot() from btrfs-progs
This patch copies the core function, btrfs_search_slot(), from
btrfs-progs.

This version has the following functionality removed:
- The ability to COW tree block
  Related code is commented out, and can be enabled in the future.

- The readahead functionality
  This is abused in kernel. Remove it completely.

With the core function in place, btrfs developers should feel at home now.

This also crossports supporting code like btrfs_previous_item() to
ctree.[ch].
