cfi-flash: Add CFG_FLASH_AUTOPROTECT_LIST

2008-04-25T13:52:14Z

This patch adds a configurable flash auto protection list that can be used to make U-Boot protect flash regions in flash_init(). The idea has been discussed on the u-boot mailing list starting on Nov 18th, 2007. Even this patch brings a new feature it is used as a bugfix for 4xx platforms where flash_init() does not completely protect the monitor's flash range in all situations. U-Boot protects the flash range from CFG_MONITOR_BASE to (CFG_MONITOR_BASE + monitor_flash_len - 1) by default. This does not include the reset vector at 0xfffffffc. Example: #define CFG_FLASH_AUTOPROTECT_LIST {{0xfff80000, 0x80000}} This config option will auto protect the last 512k of flash that contains the bootloader on board like APC405 and PMC405.

PATCH - Fix oob data copied into supplied buffer

2008-04-21T06:43:46Z

This patch correctly sets the oobavail variable and fixes a bug where the oob data was not valid when there where multiple groups in oobfree. First segment fixes a typo Second segment fixes a bug where oob data may be copied incorrectly. Third segment adds an error message when exiting due to write protect. Forth segment fixes a bug where oobavail may be set incorrectly. Signed-off-by: Troy Kisky

Clean up dataflash partitioning

2008-04-18T07:24:05Z

This patch removes the board dependent parts from "drivers/mtd/dataflash.c". Each board relying on this, will have the appropriate code in a new file, "partition.c" in the board directory. board Makefiles updated to use the file. The dataflash partitions are aligned on sector/page boundaries. The CONFIG_NEW_DF_PARTITION was used to create named partitions This is now the default operation, and the CONFIG variable is removed.

Remove conflicting NAND ID

2008-04-17T21:56:56Z

There are two NAND entries with ID 0xDC and this obviously causes problems. In the kernel, they punted the first entry, so we should do the same.

Fix OneNAND read

2008-04-14T06:11:16Z

It should access with 16-bit instead of 8-bit Now it uses the generic memcpy with 8-bit access. It means it reads wrong data from OneNAND. Signed-off-by: Kyungmin Park

cfi_flash: Support buffered writes on non-standard Spansion NOR flash

2008-04-12T06:59:09Z

Some NOR flash chip from Spansion, for example, the s29ws-n MirrorBit series require different addresses for buffered write commands. Define a configuration option to support buffered writes on those chips. A more elegant solution would be to automatically detect those chips by parsing their CFI records, but that would require introduction of a fixup table into the cfi_flash driver.

Cleanup DataFlash partition handling

2008-03-31T23:43:59Z

DataFlash partition information has become a mess. This patch defines a single partition scheme for Atmel DataFlashes. This partition scheme will be used by all AT91CAP9 and AT91SAM9 boards. Signed-off-by: Stelian Pop

MTD/CFI: flash_read64 is defined a weak function (for SPARC)

2008-03-29T05:51:04Z

SPARC has implemented __raw_readq, it reads 64-bit from any 32-bit address. SPARC CPUs implement flash_read64 which calls __raw_readq. For current SPARC architectures (LEON2 and LEON3) each read from the FLASH must lead to a cache miss. This is because FLASH can not be set non-cacheable since program code resides there, and alternatively disabling cache is poor from performance view, or doing a cache flush between each read is even poorer. Forcing a cache miss on a SPARC is done by a special instruction "lda" - load alternative space, the alternative space number (ASI) is processor implementation spcific and can be found by including .
