* | nor: don't use sector for ERASE_STARTWolfram Sang2010-06-291-2/+1
|/ | | | | | | | | | | | | | Similar to ac2d4d71ba493fd638ae0bf1a530a51c76d3c53d, copy the behaviour from Linux which does: cfi_send_gen_cmd(0x80, cfi->addr_unlock1, chip->start, map, cfi, cfi->device_type, NULL); Notice the third parameter which is simply chip->start. Needed for some SST-flashes. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* cfi_flash: fix alignment problemMarc Kleine-Budde2010-02-011-3/+7
| | | | | | | | | | | | | | | | | | | | | | This patch fixes a alignment problem which may show during this scenario: - 32 or 64 attached NOR flash - flashing an image directly from network to the nor flash The involved network driver is "smc9111.c". The data that comes from the network stack and should be written into the flash isn't 32 bit alligned (at least with this network driver). This is probably due to the 48 bit wide ethernet addresses. However the "cfi_flash.c" driver doesn't handle this situation, and accesses the not-alligned address with a 32 bit pointer. This patch fixes the problem by reducing the access width if an alligment problem between source and destination is found.

* New CFI flash driver: Fix misleading trace when unprotecting a sectorMatthias Kaehlcke2010-01-051-1/+3
| | | | | | | | | When (un)protecting a flash sector with the new CFI flash driver a trace "protect 0x..." is generated, independently of the type of operation. This is misleading in case of an unprotect. Tell the truth when unprotecting a sector. Signed-off-by: Matthias Kaehlcke <matthias@kaehlcke.net> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
