2014-01-03mtd: nand: pxa3xx: make ECC configuration checks more explicitBrian Norris1-3/+12
The Armada BCH configuration in this driver uses one of the two following ECC schemes: 16-bit correction per 2048 bytes 16-bit correction per 1024 bytes These are sufficient for mapping to the 4-bit per 512-bytes and 8-bit per 512-bytes (respectively) minimum correctability requirements of many common NAND. The current code only checks for the required strength (4-bit or 8-bit) without checking the ECC step size that is associated with that strength (and simply assumes it is 512). While that is often a safe assumption to make, let's make it explicit, since we have that information.

2014-01-03mtd: nand: pxa3xx: Add ECC BCH correctable errors detectionEzequiel Garcia1-22/+35
This commit extends the ECC correctable error detection to include ECC BCH errors. The number of BCH correctable errors can be any up to 16, and the actual value is exposed in the NDSR register. Therefore, we change some symbol names to refer to correctable or uncorrectable (instead of single-bit or double-bit as it was in the Hamming case) and while at it, cleanup the detection code slightly.

2014-01-03mtd: nand: pxa3xx: Add multiple chunk write supportEzequiel Garcia1-8/+73
This commit adds write support for large pages (4 KiB, 8 KiB). Such support is implemented by issuing a multiple command sequence, transfering a set of 2 KiB chunks per transaction. The splitted command sequence requires to send the SEQIN command independently of the PAGEPROG command and therefore it's set as an execution command. Since PAGEPROG enables ECC, each 2 KiB chunk of data is written together with ECC code at a controller-fixed location within the flash page. Currently, only devices with a 4 KiB page size has been tested.

2014-01-03mtd: nand: pxa3xx: Introduce multiple page I/O supportEzequiel Garcia1-10/+172
As preparation work to fully support large pages, this commit adds the initial infrastructure to support splitted (aka chunked) I/O operation. This commit adds support for read, and follow-up patches will add write support. When a read (aka READ0) command is issued, the driver loops issuing the same command until all the requested data is transfered, changing the 'extended' command field as needed. For instance, if the driver is required to read a 4 KiB page, using a chunk size of 2 KiB, the transaction is splitted in: 1. Monolithic read, first 2 KiB page chunk is read 2. Last naked read, second and last 2KiB page chunk is read If ECC is enabled it is calculated on each chunk transfered and added at a controller-fixed location after the data chunk that must be spare area.

In preparation to support multiple (aka chunked, aka splitted) page I/O, this commit adds 'data_buff_pos' and 'oob_buff_pos' fields to keep track of where the next read (or write) should be done.

This is important to support OOB writing, through command sequences such as: cmdfunc(mtd, NAND_CMD_SEQIN, mtd->writesize, ofs); write_buf(mtd, oob_buf, 6); cmdfunc(mtd, NAND_CMD_PAGEPROG, -1, -1); Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Tested-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

To allow future support of multiple page reading/writing, move the data buffer clean out of prepare_set_command(). This is done to prevent the data buffer from being cleaned on every command preparation, when a multiple command sequence is implemented to read/write pages larger than the FIFO size (2 KiB).

2014-01-03mtd: nand: pxa3xx: Split FIFO size from to-be-read FIFO countEzequiel Garcia1-5/+7
Introduce a fifo_size field to represent the size of the controller's FIFO buffer, and use it to distinguish that size from the amount of data bytes to be read from the FIFO. This is important to support devices with pages larger than the controller's internal FIFO, that need to read the pages in FIFO-sized chunks. In particular, the current code is at least confusing, for it mixes all the different sizes involved: FIFO size, page size and data size. This commit starts the cleaning by removing the info->page_size field that is not currently used. The host->page_size field should also be removed and use always mtd->writesize instead.

In default way, we use the ecc_strength/ecc_step size calculated by ourselves and use all the OOB area. This patch adds a new property : "fsl,use-minimum-ecc" If we enable it, we will firstly try to use the datasheet's minimum required ECC provided by the MTD layer (the ecc_strength_ds/ecc_step_ds fields in the nand_chip{}). So we may have free space in the OOB area by using the minimum ECC, and we may support JFFS2 with some SLC NANDs, such as Micron's SLC NAND. If we fail to use the minimum ECC, we will use the legacy method to calculate the ecc_strength and ecc_step size.

2013-12-29ARM: pxa: fix USB gadget driver compilation regressionLinus Walleij1-0/+2
After commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051 "ARM: pxa: delete the custom GPIO header" a compilation error was introduced in the PXA25x gadget driver. An attempt to fix the problem was made in commit b144e4ab1ef130e8bf30bcd3e529b7f35112c503 "usb: gadget: fix pxa25x compilation problems" by explictly stating the driver needs the <mach/hardware.h> header, which solved the compilation for a few boards, such as the pxa255-idp and its defconfig. However the Lubbock board has this special clause in drivers/usb/gadget/pxa25x_udc.c: This include file has an implicit dependency on <mach/irqs.h> having been included before <mach/lubbock.h> was included. Before commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051 "ARM: pxa: delete the custom GPIO header" this implicit dependency for the pxa25x_udc compile on the Lubbock was satisfied by <linux/gpio.h> implicitly including <mach/gpio.h> which was in turn including <mach/irqs.h>, apart from the earlier added <mach/hardware.h>. Fix this by having the PXA25x <mach/lubbock.h> explicitly include <mach/irqs.h>.

2013-12-26ARM: OMAP2+: hwmod_data: fix missing OMAP_INTC_START in irq dataSuman Anna2-5/+5
Commit 7d7e1eb (ARM: OMAP2+: Prepare for irqs.h removal) and commit ec2c082 (ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ) updated the way interrupts for OMAP2/3 devices are defined in the HWMOD data structures to being an index plus a fixed offset (defined by OMAP_INTC_START). Couple of irqs in the OMAP2/3 hwmod data were misconfigured completely as they were missing this OMAP_INTC_START relative offset. Add this offset back to fix the incorrect irq data for the following modules: OMAP2 - GPMC, RNG OMAP3 - GPMC, ISP MMU & IVA MMU Signed-off-by: Suman Anna <s-anna@ti.com> Fixes: 7d7e1eba7e92 ("ARM: OMAP2+: Prepare for irqs.h removal") Fixes: ec2c0825ca31 ("ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ") Cc: Tony Lindgren <tony@atomide.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2013-12-26ARM: DRA7: hwmod: Fix boot crash with DEBUG_LLRajendra Nayak1-1/+1
With commit '7dedd34: ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL' we moved from parsing cmdline to identify uart used for earlycon to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS. On DRA7 though, we seem to be missing this flag, and atleast on the DRA7 EVM where we use uart1 for console, boot fails with DEBUG_LL enabled.
