2020-12-18spi: dw: Fix driving MOSI low while recievingSean Anderson
The resting state of MOSI is high when nothing is driving it. If we drive it low while recieving, it looks like we are transmitting 0x00 instead of transmitting nothing. This can confuse slaves (like SD cards) which allow new commands to be sent over MOSI while they are returning data over MISO. The return of MOSI from 0 to 1 at the end of recieving a byte can look like a start bit and a transmission bit to an SD card. This will cause the card to become out-of-sync with the SPI device, as it thinks the device has already started transmitting two bytes of a new command. The mmc-spi driver will not detect the R1 response from the SD card, since it is sent too early, and offset by two bits. This patch fixes transfer errors when using SD cards with dw spi.

2020-12-18mtd: spinand: enable erasing of bad mtd blocksMikhail Kshevetskiy
U-Boot is able to erase bad mtd blocks on raw nand devices, but this is not true for spinand flashes. Lets enable this feature for spinand flashes as well. This is extemelly useful for flash testing. Signed-off-by: Mikhail Kshevetskiy <mikhail.kshevetskiy@oktetlabs.ru>
2020-12-18mtd: spinand: Do not erase the block before writing a bad block markerFrieder Schrempf
Currently when marking a block, we use spinand_erase_op() to erase the block before writing the marker to the OOB area. Doing so without waiting for the operation to finish can lead to the marking failing silently and no bad block marker being written to the flash. In fact we don't need to do an erase at all before writing the BBM. The ECC is disabled for raw accesses to the OOB data and we don't need to work around any issues with chips reporting ECC errors as it is known to be the case for raw NAND.

2020-12-18mtd: spinand: Explicitly use MTD_OPS_RAW to write the bad block marker to OOBFrieder Schrempf
When writing the bad block marker to the OOB area the access mode should be set to MTD_OPS_RAW as it is done for reading the marker. Currently this only works because req.mode is initialized to MTD_OPS_PLACE_OOB (0) and spinand_write_to_cache_op() checks for req.mode != MTD_OPS_AUTO_OOB. Fix this by explicitly setting req.mode to MTD_OPS_RAW.

2020-12-18mtd: spinand: Stop using spinand->oobbuf for buffering bad block markersFrieder Schrempf
For reading and writing the bad block markers, spinand->oobbuf is currently used as a buffer for the marker bytes. During the underlying read and write operations to actually get/set the content of the OOB area, the content of spinand->oobbuf is reused and changed by accessing it through spinand->oobbuf and/or spinand->databuf. This is a flaw in the original design of the SPI NAND core and at the latest from 13c15e07eedf ("mtd: spinand: Handle the case where PROGRAM LOAD does not reset the cache") on, it results in not having the bad block marker written at all, as the spinand->oobbuf is cleared to 0xff after setting the marker bytes to zero. To fix it, we now just store the two bytes for the marker on the stack and let the read/write operations copy it from/to the page buffer later.

2020-12-16x86: tangier: Find proper memory region for relocationAndy Shevchenko
It appears that U-Boot works by luck on Intel Edison board because the amount of RAM is less than 1 GB and standard way of calculating the top of it work for this configuration. However, this won't work if the amount of RAM is different and split differently in address space. We have to find the suitable window correctly. Find proper memory region for relocation by scanning MMAP SFI table in board_get_usable_ram_top() callback. According to the address map documentation the Main Memory is guaranteed to lie in the 0..2 GB range, that's why we limit search by this range.

With the updated changes to bootargs substitution[1], the zboot command needs to be updated to get its command line from an environment variable instead of a memory address. This is because the command-line string must be updated to convert %U to ${uuid}, etc. In any case it is more flexible to use a environment variable and it is best to do this before the release to avoid a subsequent change.
