* sunxi_nand_spl: Drop unnecessary temp bufHans de Goede2015-08-31-27/+8
| | | | | | | | | | | | | | | | | nand_spl_load_image() always gets called with either CONFIG_SYS_TEXT_BASE or spl_image.load_addr as destination, both of which are properly aligened, and have plenty of space for "overshooting" up to CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE bytes, as we read in CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE bytes chunks. This saves CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE (typically 1k) in SPL size, which is a lot on the total 24k we have. Note this changes the dma destination from SRAM to DRAM, so this patch updates the DDMA_DST_TYPE bits in the dma controller cfg0 reg accordingly.

* mtd: denali_spl: do not allocate page_buffer in .bss sectionMasahiro Yamada2015-08-30-20/+12
| | | | | | | | | | | | | | | | | | | Since commit 2580a2a7e719 ("mtd: nand: Increase max sizes of OOB and Page size"), three boards (ph1_ld4, ph1_pro4, ph1_sld8) fail to build with the following error message: arm-linux-gnueabi-ld.bfd: SPL image plus BSS too big They compile drivers/mtd/nand/denali_spl.c and it has a page_buffer as static data: static uint8_t page_buffer[NAND_MAX_PAGESIZE]; This buffer required 8KB in .bss section before that commit and now it has been increased to 16KB. Given limited code/memory size for SPL, it is not a good idea to allocate a page buffer statically. In the first place, the load address 'dst' can be used as a page buffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If ecc chunk data size is 512 and oobsize is bigger than 512, there is a chance that block_mark_bit_offset conflicts with bch ecc area. The following graph is modified from kernel gpmi-nand.c driver with each data block 512 bytes. We can see that Block Mark conflicts with ecc area from bch view.

* sf: Make 4K sector support configurableMarek Vasut2015-08-17-0/+19
| | | | | | | | | | | | | | | | Make the support for 4K subpage I/O on a SPI NOR flash configurable. A board which requires the SPI NOR to be accessed in larger 32KiB or 64KiB pages can disable the 4K subpage support, but by default, the support for 4K subpage I/O is enabled. The functionality of this option is the same as CONFIG_MTD_SPI_NOR_USE_4K_SECTORS in Linux. This is extremely useful in case one uses UBI on a SPI NOR flash. UBI needs at least 15k EBs and can not work on a flash which uses 4k ones, so disabling the support for 4k subpages lets UBI work on such flash.

| | | | | | | | | | | | | | | | | | Fix PIO read_byte() implementation not only used for the legacy READ ID but also the PARAM command required for proper ONFI detection. This fix is inspired by Lucas Stach's Linux Tegra NAND driver of late (not mainline yet but getting there soon I hope). I vaguely remember that those commands are special on 16-bit bus NAND (e.g. always return 8-bit data regardless) and later Linux MTD fixed/ changed the way this is handled which in turn broke once U-Boot pulled that in. Basically instead of doing PIO read regular DMA block read is now used which this patch actually fixes.

* nand: lpc32xx: add SLC NAND controller supportVladimir Zapolskiy2015-08-12-0/+177
| | | | | | | | | | | | | | | | | | | | | The change adds support of LPC32xx SLC NAND controller. LPC32xx SoC has two different mutually exclusive NAND controllers to communicate with single and multiple layer chips. This simple driver allows to specify NAND chip timings and defines custom read_buf()/write_buf() operations, because access to 8-bit data register must be 32-bit aligned. Support of hardware ECC calculation is not implemented (data correction is always done by software), since it requires a working DMA engine. The driver can be included to an SPL image.

* mtd: vf610_nfc: enable ONFI detectionStefan Agner2015-05-24-18/+49
| | | | | | | | | | This changes enable ONFI detection. The Read ID command now allows one address byte which is needed for ONFI detection. To read the ONFI parameter page, the NAND_CMD_PARAM need to be supported. The CMD code enables one command and one address byte along with reading data from flash using R/B#, as specified by ONFI.

* mtd: vf610_nfc: add 32-error correction option for HW ECCStefan Agner2015-05-24-5/+50
| | | | | | | | | Add option to choose between current 24-error correction and 32-error correction through Kconfig. 32-error correction allow to use NAND chips which require up to 8-bit error correction per 512 byte (when using 2K pages). Signed-off-by: Stefan Agner <stefan@agner.ch>

* mtd: vf610_nfc: use in-band bad block tableStefan Agner2015-05-24-27/+2
| | | | | | | | | Use in-band bad block table (NAND_BBT_NO_OOB) which allows to use the full OOB for hardare ECC purposes. Since there is no ECC correction on the OOB it is also safer to use in-band area to store the bad block table marker. Signed-off-by: Stefan Agner <stefan@agner.ch>
* mtd: vf610_nfc: implement OOB only readStefan Agner2015-05-24-59/+40
| | | | | | | | | | | | | | | | | | Implement read of OOB area only. When using column and sector size properties, only parts of the page can be read. However, this works only when hardware ECC is disabled, otherwise the ECC engine would ruin the data in the buffer. To allow OOB only reads, three points had to be addressed: - Set ECC mode per command. - Handle NAND_CMD_READOOB seperate. Make sure column and sector size is correctly set up, while disabling ECC. - Now, the OOB data end up at the beginning of the buffer. Remove the special handling of OOB (spareonly). Especially bad block scans benefit from this change. On a 512MiB SLC NAND device, the bad block scan took 1.5s less than before. Signed-off-by: Stefan Agner <stefan@agner.ch>

* mtd: vf610_nfc: remove read on SEQINStefan Agner2015-05-24-6/+8
| | | | | | | | | | | Since we do not support sub-page writes anyway, reading the page back to the controller on SEQIN command is not required. Remove the page read on SEQIN. However, the column/page values relevant to the SEQIN command, hence set the column/row address on SEQIN command. Signed-off-by: Stefan Agner <stefan@agner.ch>
* mtd: vf610_nfc: remove caching of page in bufferStefan Agner2015-05-24-10/+1
| | | | | | | | | | To improve performance we remember the current page in the buffer and avoid reading it twice. This implicit page cache increases complexity while does not increase performance in real world cases. This patch removes that feature.
