2014-10-17drivers/spi: Add support for Micron N25Q128Scott Radcliffe
Support added for Micron N25Q128 SPI flash, which has the same manufacturer id as ST Micro. Jedec ID = 0x20 0xBB 0x18. Since existing stmicro.c only compares the last device id byte, this flash is mistakenly identified as M25P128, which has ID = 0x20 0x20 0x18. To handle this situation and avoid breaking code for existing devices, a two byte .id member is added. New devices should be added to the beginning of the flash table array with .idcode = STM_ID_USE_ALT_ID and .id = the two byte jedec device id. A 4KB subsector erase capability is added and used for this new device. It requires using a different SPI op-code supported by adding .op_erase member. Previous devices defined in stmicro.c are assigned their original op-code for 64KB sector erase. N25Q128 is now working on a custom designed Bayley Bay based board. Tested by verifying the MRC fastboot cache is successfully (re)written. Note that previous devices were not retested.

In theory this effectively doubles our throughput, though the initial results were almost negligibly better. Using a logic analyzer we see a pattern of 12 clocks, ~70ns delay, 4 clocks, ~310ns delay.

2014-07-14SPI flash: Fix alignment checks in Page Program commandsKyösti Mälkki
There are two separate restrictions to take into account: Page Program command must not cross address boundaries defined by the flash part's page size. Total number of bytes for any command sent to flash part is restricted by the SPI controller capabilities. Consider CONTROLLER_PAGE_LIMIT=64, page_size=256, offset=62, len=4. This write would be split at offset 64 for no reason. Consider CONTROLLER_PAGE_LIMIT=40, page_size=256, offset=254, len=4. This write would not be split at page boundary as required. We do not really hit the second case. Nevertheless, CONTROLLER_PAGE_LIMIT is a misnomer for the maximum payload length supported by the SPI controller and is removed in a followup.

2014-07-05spi: Change spi_xfer to work in units of bytes instead of bits.Gabe Black
Whenever spi_xfer is called and whenver it's implemented, the natural unit for the amount of data being transfered is bytes.

2014-07-05drivers/spi: Reduce the per loop delay of spi_flash_cmd_poll_bit()Dave Frodin
At the end of some SPI operations the SPI device needs to be polled to determine if it is done with the operation. For SPI data writes the predicted time of that operation could be less than 10us. The current per loop delay of 500us is adding too much delay. This change replaces the delay(x) in the do-while loop with a timer so that the actual timeout value won't be lengthened by the delay of reading the SPI device.

2012-12-12Claim the SPI bus before writes if the IMC ROM is presentMartin Roth
The SB800 and Hudson now support adding the IMC ROM which runs from the same chip as coreboot. When the IMC is running, write or erase commands sent to the spi bus will fail, and the IMC will die. To fix this, we send a request to the IMC to stop fetching from the SPI rom while we write to it. This process (in one form or another) is required for writes to the SPI bus while the IMC is running. Because the IMC can take up to 500ms to respond every time we claim the bus, this patch tries to keep the number of times we need to do that to a minimum. We only need to claim the bus on writes, and using a counter for the semaphore allows us to call in once to claim the bus at the beginning of a number of transactions and it will stay claimed until we release it at the end of the transactions. Claim() - takes up to 500ms hit claim() - no delay erase() release() claim() - no delay write() release() Release() Change-Id: I4e003c5122a2ed47abce57ab8b92dee6aa4713ed Signed-off-by: Martin Roth <martin@se-eng.com> Reviewed-on: http://review.coreboot.org/1976 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>
