2013-08-05mtd: bcm63xxpart: use nvram for PSI sizeJonas Gorski
Read out the SPI size from nvram instead of defaulting to 64KiB — some vendors actually use values larger than the "max" value of 64.

2012-11-21mtd: bcm63xxpart: make fixed part length calculation more genericJonas Gorski
The CFE does not use 4K sectors even if the flash supports it, so for the fixed partitions like CFE itself or NVRAM the erase block size is always 64k or bigger.

2012-05-13mtd: bcm63xxpart: handle Broadcom partition orderJonas Gorski
The original Broadcom partition order has the root fs in front of the kernel, which resulted in miscalculated partition sizes. Detect when such an image is on the flash and also reorder the partitions accordingly.

2012-01-09mtd: bcm63xxpart: check the image tag's crc32Jonas Gorski
Only use the values from the image tag if it is valid. Always create the CFE, NVRAM and linux partitions, to allow flashing a new image even if the old is invalid without overwriting CFE or NVRAM.

2012-01-09mtd: bcm63xxpart: don't assume NVRAM is always the fourth partitionJonas Gorski
Instead of referencing the sizes of fixed partitions, use the precomputed CFE/NVRAM lengths. Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2012-01-09mtd: bcm63xxpart: make sure CFE and NVRAM partitions are at least 64KiBJonas Gorski
The CFE boot loader on BCM63XX platforms assumes itself and the NVRAM partition to be 64 KiB (or erase block sized, if larger). Ensure this assumption is also met when creating the partitions to prevent accidential erasure of CFE or NVRAM.

2012-01-09mtd: bcm63xxpart: check version marker string for newer CFEsJonas Gorski
Recent CFEs do not contain the CFE1CFE1 magic anymore, so check for the "cfe-v" version marker string instead. As very old CFEs do not have this string, leave the CFE1CFE1 magic as a fallback for detection.

2012-01-09mtd: maps: bcm963xx-flash: make CFE partition parsing an mtd parserJonas Gorski
Recent BCM63XX devices support a variety of flash types (parallel, SPI, NAND) and share the partition layout. To prevent code duplication make the CFE partition parsing code a stand alone mtd parser to allow SPI or NAND flash drivers to use it.
