* mtd: nand-bb: Also print raw position in debug messagesSascha Hauer2015-02-101-2/+4
| | | | | | | When debugging the nand-bb devices also the raw position on the device is interesting, print it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: nand-bb: Fix test for bad block when readingSascha Hauer2015-02-101-1/+1
| | | | | | | | in nand_bb_read() 'offset' contains the virtual position on the device, but we have to test for a bad block on the raw physical position, so use bb->offset instead of offset Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: nand-bb: fix erasing bb devices with bad blocksSascha Hauer2015-02-101-3/+21
| | | | | | | mtd_erase does not skip bad blocks, we must skip them in nand_bb_erase instead. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: nand-bb: Fix accesses beyond deviceSascha Hauer2015-02-101-0/+16
| | | | | | | | | When a block is marked bad after the bb device has been created the real size of the bb device is smaller than the calculated size on creation. In this case we can't rely on the upper layers anymore that they won't pass read/write sizes in that fit into the device. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mtd: Fix allowing to erase bad blocks on partitionsSascha Hauer2015-02-101-3/+3
| | | | | | | | | Partitions are mtd devices themselves, but the 'erasebad' parameter is only set to the master mtd device. To allow to erase bad blocks on partitions test the master device instead of the partition devices. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is broken since: | commit 00f119a29387cfb1b188fcc4daa4aa94186ac7a9 | Author: Sascha Hauer <s.hauer@pengutronix.de> | Date: Fri Aug 1 14:09:48 2014 +0200 | | mtd: omap gpmc: fix ecc bytes/size | | The ecc bytes / size are per subpage, not per page. | | Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> The ecc code in omap_correct_data() expects to correct a whole page at once, so we must tell the nand layer that we have 4 * 13 bytes of ecc bytes and 4 * 512 bytes of ecc size. Otherwise the NAND layer will iterate over 512 byte steps over a page and call the .correct callback each time. This only works for 2k pagesize and needs revisit once other page sizes shall be supported. It would be better to tell the nand layer the real ecc bytes (13) and ecc size (512) instead and drop the iteration in omap_correct_bch(). However, this needs better testing so it isn't done here now. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the smcs family chips 91c94, 91c96, 91c100, 91c111 share almost the same behavior and register sets. The noticeable exceptions are coped with in this patch, ie : - 91c94 and 91c96 only have an internal 10 Mbps phy The registers used for phy discovery on later chips will corrupt the 91c96 state. - 91c94 and 91c96 have a control and config register quite different from their 91c1xx conterparts A platform data user defined couple of registers is introduced. If these values are 0, 91c1xx legacy behavior is assumed. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | net: smc1111: add 16 bits accessors, allow address shiftRobert Jarzmik2015-02-041-42/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Smc network IPs can be wired up in different funny ways. For example the lubbock pxa25x development platform wires all address lines shifted by 2, ie. bus A2 is smc91c96 A0, bus A3 is smc91c96 A1 etc ... In order to cope with the different possible combination, add a shift parameter for addresses. By default, the old behaviour using the 32 bit accesses is kept.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the SMC1111 has a shared pool of 2k memory buckets for both transmission and reception, and as there are variants which have as few as 4 buckets in total, the memory pool can be hogged by unclaimed receptions, and impeed any further transmission. This happens on the zylonite pxa board, where 4 packets, most probably icmp and arp, fill the 4 buckets, preventing any further ethernet transmission, and stalling the driver. The fix is rather rough : whenever all the buckets are filled by reception packets, and if a transmission is required, the transmission code path will empty up all received packets.

The patch was tested on qemu, but qemu malta board is tolerant of using physical addresses for accesing to device (Ingenic JZ4755 and JZ4780 processors are tolerant too!). But other CPUs (e.g. Loongson LS1B) can throw an exception in this situation. Additional physical address to virtual address translation on MIPS is needed.
