The AM64x SR2.0 SK board uses "AM64B-SKEVM" as the EEPROM identifier. This board is similar to the AM64x SKEVM except that it has a new PMIC that will be enabled in the future and consequently could use a different device tree file in the future. For now we treat the board same as an AM64x SK. Signed-off-by: Judith Mendez <jm@ti.com> Acked-by: Andrew Davis <afd@ti.com> Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com>
Add method to remove video driver before loading u-boot proper. When bootstage changes from SPL to u-boot proper, noo method is called to remove video driver, and at u-boot proper if video driver is not enabled, the video driver starts displaying garbage on the screen, because there is no reserved space for video and the frame buffer gets u-boot proper data written.

Change splashimage which is bmp image loadaddr to 0x80200000 since stack is situated at 0x80477660 as splash framework requires bmp image to be present above stack. Change splashsource to sf to support loading bmp image from ospi flash memory. Signed-off-by: Nikhil M Jain <n-jain1@ti.com>
To enable splash at A53 SPL, need to do memory map changes which
involves locate stack above malloc and have enough space to load bmp
image above stack. To load a 1920X1200 image a minimum of 8.8MB space is
needed, to support it move malloc down to 0x80b80000 from 0x80480000 and
bss to 0x80c80000 to have 1MB buffer between malloc and BSS.
Observed SPL size 195KB, CONFIG_SPL_SIZE_LIMIT set to 256KB.
Observed stack size 1904Bytes, CONFIG_SPL_SIZE_LIMIT_PROVIDE_STACK set
to 2KB.
CONFIG_SPL_SYS_REPORT_STACK_F_USAGE config sets stack above the malloc
and reports for stack overflow.

btrfs_read_extent_reg correctly computed the extent offset in the
BTRFS_COMPRESS_NONE case, but did not account for the 'offset - key.offset'
part correctly in the compressed case, making the function read
incorrect data.
In the case I examined, the last 4k of a file was corrupted and
contained data from a few blocks prior, e.g. reading a 10k file with a
single extent:
btrfs_file_read()
-> btrfs_read_extent_reg
(aligned part loop, until 8k)
-> read_and_truncate_page
-> btrfs_read_extent_reg
(re-reads the last extent from 8k to the end,
incorrectly reading the first 2k of data)
This can be reproduced as follow:
$ truncate -s 200M btr
$ mount btr -o compress /mnt
$ pat() { dd if=/dev/zero bs=1M count=$1 iflag=count_bytes status=none | tr '\0' "\\$2"; }
$ { pat 4K 1; pat 4K 2; pat 2K 3; } > /mnt/file
$ sync
$ filefrag -v /mnt/file
File size of /mnt/file is 10240 (3 blocks of 4096 bytes)
ext: logical_offset: physical_offset: length: expected: flags:
0: 0.. 2: 3328.. 3330: 3: last,encoded,eof
$ umount /mnt
Then in u-boot:
=> load scsi 0 2000000 file
10240 bytes read in 3 ms (3.3 MiB/s)
=> md 2001ff0
02001ff0: 02020202 02020202 02020202 02020202 ................
02002000: 01010101 01010101 01010101 01010101 ................
02002010: 01010101 01010101 01010101 01010101 ................
(02002000 onwards should contain '03' pattern but went back to 01,
start of the extent)
After patch, data is read properly:
=> md 2001ff0
02001ff0: 02020202 02020202 02020202 02020202 ................
02002000: 03030303 03030303 03030303 03030303 ................
02002010: 03030303 03030303 03030303 03030303 ................
Note that the code previously (before commit e3427184f38a ("fs: btrfs:
Implement btrfs_file_read()")) did not split that read in two, so
this is a regression even if the previous code might not have been
handling offsets correctly either (something that booted now fails to
boot)

- cmd: tlv_eeprom: Misc cleanups & improvements (Josua)
Move the handler for "tlv_eeprom dev X" command to the beginning of do_tlv_eeprom, to allow using it before issuing a "read" command for currently selected eeprom. Also remove the check if eeprom exists, since that can only work after the first execution of read_eeprom triggered device lookup. Instead accept values up to the defined array size (MAX_TLV_DEVICES).
