| | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the double defined manufacturer defines from jedec_flash.c. Since the common defines in flash.h are 32bit we now need the (16) cast.

* | flash/cfi_flash: Use virtual sector start address, not physBecky Bruce2009-02-05-29/+24
|/ | | | | | | | | | | | | | | | | | | | | | | | include/flash.h was commented to say that the address in flash_info->start was a physical address. However, from u-boot's point of view, and looking at most flash code, it makes more sense for this to be a virtual address. So I corrected the comment to indicate that this was a virtual address. The only flash driver that was actually treating the address as physical was the mtd/cfi_flash driver. However, this code was using it inconsistently as it actually directly dereferenced the "start" element, while it used map_physmem to get a virtual address in other places. I changed this driver so that the code which initializes the info->start field calls map_physmem to get a virtual address, eliminating the need for further map_physmem calls. The code is now consistent. The *only* place a physical address should be used is when defining the flash banks list that is used to initialize the flash_info struct, usually found in the board config file.

Modeled after flash_fixup_amd, this patch handles the geometry reversal or erase sectors that exist for ST Micro (now Numonyx) M29W320ET flash.

* NAND: rename NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPSWolfgang Grandegger2009-01-23-2/+2
| | | | | | | | | | | | | | | | This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and changes the default from 8 to 1 for the legacy and the new MTD NAND layer. This allows to remove all NAND_MAX_CHIPS definitions in the board config files because none of the boards use multi chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440 define #define NAND_MAX_CHIPS CONFIG_SYS_MAX_NAND_DEVICE but that's bogus and did not work anyhow.

| * NAND FSL elbc: Use virt_to_phys to determine which bank is in useKumar Gala2008-12-19-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | The current code that determines which bank/chipselect is used for a given NAND instance only worked for 32-bit addresses and assumed a 1:1 mapping. This breaks in 36-bit physical configs.

* CFI Driver: Fix "flash not ready" problemWolfgang Denk2008-10-31-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem on systems where the NOR flash is attached to a 64 bit bus. The toggle bit detection in flash_toggle() is based on the assumption that the same flash address is read twice without any other interjacent flash accesses. However, on 32 bit systems the function flash_read64() [as currently implemented] does not perform an atomic 64 bit read - instead, this is broken down into two 32 bit read accesses on addresses "addr" and "addr + 4". So instead of reading a 64 bit value twice from "addr", we see a sequence of 4 32 bit reads from "addr", "addr + 4", "addr", and "addr + 4". The consequence is that flash_toggle() fails to work. This patch implements a simple, but somewhat ugly solution, as it avoids the use of flash_read64() in this critical place (by breaking it down manually into 32 bit read operations) instead of rewriting flash_read64() such to perform atomic 64 bit reads as one could expect. However, such a rewrite would require the use of floating point load operations, which becomes pretty complex: save MSR; set Floating Point Enable bit in MSR; use "lfd" instruction to perform atomic 64 bit read; use "stfd" to store value to temporary variable on stack; load u64 value from temporary variable; restore saved MSR; return u64 value; The benefit-cost ratio of such an implementation was considered too bad to actually attempt this, especially as we can expect that such an implementation would not only have a bigger memory footprint but also cause a performance degradation.
