2020-09-09ARM: dts: stm32: Pull UART4 RX high on AV96Marek Vasut1-0/+2
There is no dedicated pull resistor on the AV96 UART4 (console UART) pin. In case there is no UART adapter installed on the AV96, the line is floating and can trigger reception of garbage characters, which in turn can abort U-Boot autoboot. Add default pull up to mitigate this problem.

2020-09-08bcmgenet: fix DMA buffer managementJason Wessel1-8/+9
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.

Along this rework, some small corner cases fixed: - Subvolume tree mtime Mtime of a subvolume tree is recorded in its root item, since there is no INODE_ITEM for it.

This patch uses generic code from btrfs-progs to read one super block from block device. To support the btrfs-progs coding style, the following is also crossported: - BTRFS_SETGET_FUNC for btrfs_super_block - btrfs_check_super() function - Move btrfs_read_superblock() to disk-io.[ch] Since super.c only contains pretty small amount of code, and the extra check will be covered in later root read patches. Differences between this implementation and btrfs-progs: - No sbflags/sb_bytenr support Since we only need to read the primary super block (like kernel), sbflags/sb_bytenr used by super block recovery is not needed. This also changes the following behavior of U-Boot btrfs: - Only reads the primary super block The old implementation reads all 3 super blocks, and also one non-existing backup. This is not correct, especially if there is another filesystem created on the device but old superblocks are not rewritten. Just like kernel, we only check the primary super block.
