* fs/fat: Improve error handlingKyle Moffett2012-01-05-4/+14
| | | | | | | | | | | | | | | | | | | | The FAT filesystem fails silently in inexplicable ways when given a filesystem with a block-size that does not match the device sector size. In theory this is not an unsupportable combination but requires a major rewrite of a lot of the filesystem. Until that occurs, the filesystem should detect that scenario and display a helpful error message. This scenario in particular occurred on a 512-byte blocksize FAT fs stored in an El-Torito boot volume on a CD-ROM (2048-byte sector size). Additionally, in many circumstances the ->block_read method will not return a negative number to indicate an error but instead return 0 to indicate the number of blocks successfully read (IE: None). The FAT filesystem should defensively check to ensure that it got all of the sectors that it asked for when reading. Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com>
* fs/fat: Fix FAT detection to support non-DOS partition tablesKyle Moffett2012-01-05-63/+52
| | | | | | | | | | | | | | | | | | | The FAT filesystem code currently ends up requiring that the partition table be a DOS MBR, as it checks for the DOS 0x55 0xAA signature on the partition table (which may be Mac, EFI, ISO9660, etc) before actually computing the partition offset. This fixes support for accessing a FAT filesystem in an ISO9660 boot volume (El-Torito format) by reordering the filesystem checks and reading the 0x55 0xAA "DOS boot signature" and FAT/FAT32 magic number from the first sector of the partition instead of from sector 0.

* ext2: Cache line align indirection buffersSimon Glass2012-01-05-6/+12

* tools/env: allow overwrite of ethaddr on defaultGrant Erickson2012-01-05-2/+11
| | | | | | | | | | | | | This patch allows the U-Boot user space companion utility, fw_setenv, to overwrite the 'ethaddr' key/value pair if the current value is set to a per-board-configured default. This change allows 'fw_setenv' to match the behavior of 'setenv' / 'env set' on the U-Boot command line. Signed-off-by: Grant Erickson <marathon96@gmail.com> Fixed excessive white space.

| * tegra2: Plumb in SPI/UART switch codeSimon Glass2011-12-24-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Seaboard the UART and SPI interfere with each other. This causes the UART to receive spurious zero bytes after SPI transactions and also means that SPI can corrupt a few output characters when it starts up if they are still in the UART buffer. This updates the board to use the SPI/UART switch to avoid the problem. For now this feature is turned off since it needs changes to the NS16550 UART to operate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tegra2 Seaboard has the unfortunate feature that SPI and the console UART are multiplexed on the same pins. We need to switch between one and the other during SPI and console activity. This new file implements a switch and keeps track of which peripheral owns the pins. It also flips over the controlling GPIO as needed Since we are adding a second file to board/nvidia/common, we create a proper Makefile there and remove the direct board.o include from board/nvidia/seaboard/Makefile Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
