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>
2012-03-04sf: inline data constantsMike Frysinger
I imagine much of these constants are due to copy & pasting previous drivers rather than an actual reflection of the hardware layout. At any rate, inline the info that we don't care about externally as it shrinks things nicely. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-07-20sf: spansion: inline useless id definesMike Frysinger
No need for dedicated defines when these really only get used once. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-07-20sf: drop unused/duplicate command definesMike Frysinger
In an effort to unify the spi flash drivers further, drop all the unused and/or duplicate command defines. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-02-12sf: eeprom_m95xxx: set a sane default timeoutMike Frysinger
Every board currently defines this to the same value, so just default to that to avoid having to make everyone do the same thing. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-12-05sf: fix erase debug outputVadim Bendebury
We want to show the length, so multiplying by sector size makes no sense. This is a hold over from the erase code before the big refactor. Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-09-21sf: fix debug format string warningVadim Bendebury
On some systems, we get a warning when %lu is used with size_t's, so use the correct format string. Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Add support of MX25L4005 and MX25L8005 according to the datasheet http://www.mct.net/download/macronix/mx25l8005.pdf This patch has been tested with MX25L4005 and MX25L8005 Signed-off-by: Macpaul Lin <macpaul@andestech.com>
2011-07-26sf: sst: support newer standardized flashesMike Frysinger
Newer SST flashes have dropped the Auto Address Increment (AAI) word programming (WP) modes in favor of the standard page programming mode that most flashes now support. So add a flags field to the different flashes to support both modes with new and old styles. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-26sf: unify write disable commandsMike Frysinger
Every spi flash uses the same write disable command, so unify this in the common code. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Fixed commit message. Signed-off-by: Wolfgang Denk <wd@denx.de>

2011-07-26sf: kill off now-unused local stateMike Frysinger
Now that the common spi_flash structure tracks all the info that these drivers need, kill off their local state indirection and use just what the common code provides. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-26sf: unify write funcsMike Frysinger
Once we add a new page_size field for write lengths, we can unify the write methods for most of the spi flash drivers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-04-12sf: sst: setup read funcMike Frysinger
The previous unification patch missed setting up the sst read func. 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).

2011-04-11sf: atmel: undo unification of status pollingMike Frysinger
The AT45 flashes are completely different (at the command set and status register level) from all other SPI flashes, so we can't unify their logic with common code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-04-11sf: unify status polling for ready bitMike Frysinger
All of the spi flash drivers implement the status register polling for detecting the device ready state, so unify them all in a new helper function -- spi_flash_wait_ready. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-11sf: unify read/write helpersMike Frysinger
These functions largely do the same exact thing, so unify them all into one basic function. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

2010-10-12sf: turn probe switch into a lookup tableReinhard Meyer
This allows for arbitrarily long manufacturer ids following the JEDEC standard of 0x7f continuation bytes. It also makes adding new entries easier as it's just one element in an array. The downside is that it increases code size a bit, but we're talking ~50 bytes. Signed-off-by: Reinhard Meyer <u-boot@emk-elektronik.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-06sf: spansion: add support for S25FL032P partsDavid Jander

2010-10-06sf: spansion: fixing erasing when sector size >64KiBMarc-André Hébert
The spansion_erase currently only works when the sector size is 64KB. cmd[1] should contain the higher 8 bit of the 24 bit address of the sector to be erased. Currently it is holding the sector index to be erased which happens to be the same thing when the sector size is 64KB.

2010-06-30sf: move useful messages from debug to printfMike Frysinger
At the moment, the default SPI flash subsystem is quite terse. Errors and successes both result in a generic message. So move the useful errors and useful successes to printf output by default. While we're here, also convert the messages to use print_size(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
