config MTD_PARSER_TRX

|
TRX is a firmware format used by Broadcom on their devices. It
|
|
may contain up to 3/4 partitions (depending on the version).
|
|
This driver will parse TRX header and report at least two partitions:
|
|
kernel and rootfs.

This provides the read-only FTL logic necessary to read the partition
|
|
table from the NAND flash of Sharp SL Series (Zaurus) and the MTD
|
|
partition parser using this code.

tristate "RedBoot partition table parsing"
|
|
help
|
|
RedBoot is a ROM monitor and bootloader which deals with multiple
|
|
'images' in flash devices by putting a table one of the erase
|
|
blocks on the device, similar to a partition table, which gives
|
|
the offsets, lengths and names of all the images stored in the
|
|
flash.
|
|
|
|
If you need code which can detect and parse this table, and register
|
|
MTD 'partitions' corresponding to each image in the table, enable
|
|
this option.
|
|
|
|
You will still need the parsing functions to be called by the driver
|
|
for your particular device. It won't happen automatically. The
|
|
SA1100 map driver (CONFIG_MTD_SA1100) has an option for this, for
|
|
example.

|
|
This option is the Linux counterpart to the
|
|
CYGNUM_REDBOOT_FIS_DIRECTORY_BLOCK RedBoot compile time
|
|
option.
|
|
|
|
The option specifies which Flash sectors holds the RedBoot
|
|
partition table. A zero or positive value gives an absolute
|
|
erase block number. A negative value specifies a number of
|
|
sectors before the end of the device.
|
|
|
|
For example "2" means block number 2, "-1" means the last
|
|
block and "-2" means the penultimate block.
