2013-10-07sf: Remove unneeded flash drivers filesJagannadha Sutradharudu Teki

2013-10-07sf: probe: Add support for SST_WPJagannadha Sutradharudu Teki
Most of the SST flashes needs to write up using SST_WP, AAI Word Program, so added a flag param on spi_flash_params table. SST flashes, which supports SST_WP need to use a WP write sst_write_wp instead of common flash write. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com>

2013-06-23sf: Unify spi_flash write codeJagannadha Sutradharudu Teki
Move common flash write code into spi_flash_write_common(). Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com> Acked-by: Simon Glass <sjg@chromium.org>
2013-06-23sf: Add flag status register polling supportJagannadha Sutradharudu Teki
Flag status register polling is required for micron 512Mb flash devices onwards, for performing erase/program operations. Like polling for WIP(Write-In-Progress) bit in read status register, spi_flash_cmd_wait_ready will poll for PEC(Program-Erase-Control) bit in flag status register.

2013-06-23sf: Remove spi_flash_cmd_poll_bit()Jagannadha Sutradharudu Teki
There is no other call other than spi_flash_cmd_wait_ready(), hence removed spi_flash_cmd_poll_bit and use the poll status code spi_flash_cmd_wait_ready() itself. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2013-06-23sf: Add bank addr code in CONFIG_SPI_FLASH_BARJagannadha Sutradharudu Teki
Defined bank addr code on CONFIG_SPI_FLASH_BAR macro, to reduce the size for existing boards which has < 16Mbytes SPI flashes. It's upto user which has provision to use the bank addr code for flashes which has > 16Mbytes.

2013-06-23sf: Read flash bank addr register at probe timeJagannadha Sutradharudu Teki
Read the flash bank addr register to get the state of bank in a perticular flash. and also bank write happens only when there is a change in bank selection from user. bank read only valid for flashes which has > 16Mbytes those are opearted in 3-byte addr mode, each bank occupies 16Mytes. Suppose if the flash has 64Mbytes size consists of 4 banks like bank0, bank1, bank2 and bank3.

2013-06-23sf: Discover the bank addr commandsJagannadha Sutradharudu Teki
Bank/Extended addr commands are specific to particular flash vendor so discover them based on the idocode0. Assign the discovered bank commands to spi_flash members so-that the bank read/write will use their specific operations. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com>
2013-06-23sf: Add bank address register writing supportJagannadha Sutradharudu Teki
This patch provides support to program a flash bank address register. extended/bank address register contains an information to access the 4th byte addressing in 3-byte address mode. reff' the spec for more details about bank addr register in Page-63, Table 8.16 http://www.spansion.com/Support/Datasheets/S25FL128S_256S_00.pdf Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2012-03-04sf: unify status register writing (and thus block unlocking)Mike Frysinger
The only two drivers to write the status register do it in the same way, so unify the implementations. This also makes the block unlock logic the same. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-04sf: unify erase commandsMike Frysinger
Analysis of the flash drivers shows that they all use 0x20 if the erase size is 4KiB, or 0xd8 if it's larger. So with this info in hand, we can unify all the erase functionality in one place. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-04-12sf: add struct spi_flash.sector_size parameterRichard Retanubun
This patch adds a new member to struct spi_flash (u16 sector_size) and updates the spi flash drivers to start populating it. This parameter can be used by spi flash commands that need to round up units of operation to the flash's sector_size. Having this number in one place also allows duplicated code to be further collapsed into one common location (such as erase parameter and the detected message).

2009-04-02sf: set common timeouts in seconds, not millisecondsMike Frysinger
Since timeouts are only hit when there is a problem in the system, we don't want to prematurely timeout on a functioning setup. Thus having low timeouts (in milliseconds) doesn't gain us anything in the production case, but rather increases likely hood of causing problems where none otherwise exist.
