2005-07-12[MTD] Make XIP support depend on CONFIG_ARMThomas Gleixner
ARM is the only known user of this at the moment. Prevent allyes builds for other archs from failing Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-07-05[MTD] cfi_cmdset_0002: Remove bogus includeThomas Gleixner
Including asm/hardware.h has to be done in linux/mtd/xip.h. Otherwise it breaks allyes compiles. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-05-23[MTD] CFI-0002 - Improve error checkingEric W. Biedermann
Check for errors besides infinite loops when writing and erasing. Signed-off-by: Eric W. Biederman <ebiederman@lnxi.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2005-05-23[MTD] CFI flash locking reorg for XIPNicolas Pitre
This reworks the XIP locking to make sure no lock primitive is ever called from XIP disabled paths even if in theory they should not cause any reschedule. Relying on the current spinlock implementation is rather fragile and not especially clean from an abstraction pov. The recent RT work makes it even more obvious.

2005-05-23[MTD] Add reboot notifier to Intel NOR flash driverNicolas Pitre
to make sure the flash is in array mode whenever we're about to reboot. This is especially useful to allow "soft" reboot to work which consists of branching back into the bootloader. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

Skip jiffy delay after each block lock/unlock for Intel CFI flash with the "Instant Individual Block Locking" feature bit set. Signed-off-by: Todd Poynor <tpoynor@mvista.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

oldstate has to be reset to FL_READY after sync completion. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2005-05-23[MTD] cfi_cmdset_0001: Fix the buggy status check. Thomas Gleixner
The change makes the code endianess aware and replaces the bogus nested loop to or the status flags together. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-05-23[MTD] Fixup probing logic for single 16bit devicesBen Dooks
The change to the generic probe to look for the smallest width of chip first is causing some problems on boards with a single 16bit device. The problem seems to be the jedec_match() is truncating the device-id read from the table to match against the one read from the hardware, causing a match against the partial id of some chips with 16bit IDs (such as the SST39LF160) This fixes things for my own board, but something may need to be done if the same problem is exhibited for chips with an 8bit ID Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2005-05-23[MTD] Support for protection register support on Intel FLASH chipsNicolas Pitre
This enables support for reading, writing and locking so called "Protection Registers" present on some flash chips. A subset of them are pre-programmed at the factory with a unique set of values. The rest is user-programmable. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-05-23[MTD] amd_flash: Fix chip ID clashJonas Holmberg
* Removed table entry for AM29BDS643D, since device ID clashes with AM29DL640G and both chips support CFI. Signed-off-by: Jonas Holmberg <jonas.holmberg@axis.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2005-05-23[MTD] Fix MTD device probingRussell King
Try larger numbers of chips before smaller numbers of chips across the bus width. This means we'll avoid misdetecting a 2 x16 array as 1 x32 if the high 16-bits happen to read as zeros in the QRY area.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
