* cfi_flash: Add cmdset-specific init functionsHaavard Skinnemoen2007-12-171-63/+111
| | | | | | | | | Move things like reading JEDEC IDs and fixing up geometry reversal into separate functions. The geometry reversal fixup is now performed by altering the qry structure directly, which makes the sector init code slightly cleaner. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* cfi_flash: Read whole QRY structure in one goHaavard Skinnemoen2007-12-171-86/+90
| | | | | | | | Read out the whole CFI Standard Query structure after successful cfi identification. This allows subsequent code to access this information directly without having to go through flash_read_uchar() and friends. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* cfi_flash: Use map_physmem() and unmap_physmem()Haavard Skinnemoen2007-12-131-60/+109
| | | | | | | | Use map_physmem() and unmap_physmem() to convert from physical to virtual addresses. This gives the arch a chance to provide an uncached mapping for flash accesses. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* cfi_flash: Introduce read and write accessorsHaavard Skinnemoen2007-12-131-78/+127
| | | | | | | | | Introduce flash_read{8,16,32,64) and flash_write{8,16,32,64} and use them to access the flash memory. This makes it clearer when the flash is actually being accessed; merely dereferencing a volatile pointer looks just like any other kind of access.

* cfi_flash: Reorder functions and eliminate extra prototypesHaavard Skinnemoen2007-12-131-687/+656
| | | | | | | | | Reorder the functions in cfi_flash.c so that each function only uses functions that have been defined before it. This allows the static prototype declarations near the top to be eliminated and might allow gcc to do a better job inlining functions. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* cfi_flash: Make some needlessly global functions staticHaavard Skinnemoen2007-12-131-7/+9
| | | | | | Make functions not declared in any header file static. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* cfi_flash: Break long linesHaavard Skinnemoen2007-12-131-115/+189
| | | | | | | | | This patch tries to keep all lines in the cfi_flash driver below 80 columns. There are a few lines left which don't fit this requirement because I couldn't find any trivial way to break them (i.e. it would take some restructuring, which I intend to do in a later patch.)

* CFI: synchronize command offsets with Linux CFI driverBartlomiej Sieka2007-12-131-3/+20
| | | | | | Fixes non-working CFI Flash on the Inka4x0 board. Signed-off-by: Bartlomiej Sieka <tur@semihalf.com>
* CFI: Coding style cleanupStefan Roese2007-12-081-5/+4

* CFI: support JEDEC flash roms in CFI-flash frameworkMichael Schwingen2007-12-083-12/+411
| | | | | | | | | The following patch adds support for non-CFI flash ROMS, by hooking into the CFI flash code and using most of its code, as recently discussed here in the thread "Mixing CFI and non-CFI flashs".
