This EEPROM is hardware-write-protected and used to persist key
information such as the serial number and MAC addresses even if the
primary environment sector in NOR FLASH is overwritten.
During manufacturing, the environment is initialized from Linux and then
the key parameters copied to the EEPROM via U-Boot:
env export -c -s 0x2000 $loadaddr serial# macaddr mac1addr mac2addr
eeprom write $loadaddr 0x0000 0x2000
The chip is then locked via hardware for delivery.
When doing a field U-Boot upgrade, the environment is erased and reset
to the defaults to avoid problems with "hwconfig" changes, etc. After
loading the new U-Boot image, the hardware data is reloaded:
i2c dev 0
eeprom read $loadaddr 0x0000 0x2000
env import -c $loadaddr 0x2000
saveenv
The first three commands are saved in the "restore_eeprom" variable for
user convenience. (EG: "run restore_eeprom && saveenv")

Most of the ethernet connections are internal links with specialized
hardware and are not useful for "dhcp" or general-purpose networking;
U-Boot should not be cycling through them. Force the primary external
network interface in "ethprime" and disable the interface cycling with
"ethrotate=no".
Additionally, the environment variable "preboot" has its own config
option and means something entirely different from what the HWW-1U-1A
variable was intended for. Rename the board variable to "setbootargs"
to avoid potential confusion.
Finally, fix an incorrect address for the kernel in FLASH memory.

When performing large bulk reads from a CD or DVD using the U-Boot
usb_storage driver, it generates requests of up to 20 blocks at a time.
With a standard 512-byte block size, that is 10240 bytes and within the
limit of U-Boot's EHCI driver (maximum 5 pages at 4k per page).
Unfortunately CD-ROM media has a 2048-byte blocksize, resulting in a
maximum transfer size of 40960 bytes, which does not fit.
Since the EHCI specification is impossibly obtuse and far beyond my
comprehension, I chose to dynamically compute the limit based on the
blocksize.
Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com>
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>
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.

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.
