* ENGR00315499-19 Fix eMMC fast boot hang issueYe.Li2015-04-29-9/+28
| | | | | | | | | | | | | | | | | | When booting in eMMC fast boot, the uboot v2013.04 always hangs. The root cause is that MMC host does not exit from boot mode after bootrom loading image. So the first command 'CMD0' sent in uboot will pull down the CMD line to low and cause errors. This patch cleans the MMC boot register in "mmc_init" to put the MMC host back to normal mode.

* MLK-10215 Add elan init in i.MX6SL-EVK boardHaibo Chen2015-04-29-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | EPDC board contain a elan touch screen, this screen is a i2c slave. If this EPDC board connect to i.MX6SL-EVK board, after uboot boot up, if we do i2c operation, like i2c probe, then the i2c bus block. This is due to the elan touch screen i2c slave. This device needs to do some initialization opearation before its i2c operation, otherwise this i2c device pull down the i2c clk line, and make the i2c bus hang. This means elan needs a special flow on i2c before its address is acked, otherwise the i2c bus will be hang. This patch is a workaround, it add a void function which is defined as a weak symbol in i2c driver, and it is called before every i2c operation. In mx6slevk, this function was overwrite to execute elan initialization. So that, for mx6slevk board, it will initialize elan before every i2c operation, but for other boards, it just work as before.

| | | | | | | | | | | | | | | | | | | | | | | | DCIMVAC is upgraded to DCCIMVAC for the individual processor (Cortex-A7) that the DCIMVAC is executed on. We should follow the linux dma follow. Before DMA read, first invalidate dcache then after DMA read, invalidate dcache again. With the DMA direction DMA_FROM_DEVICE, the dcache need be invalidated again after the DMA completion. The reason is that we need explicity make sure the dcache been invalidated thus to get the DMA'ed memory correctly from the physical memory. Any cache-line fill during the DMA operations such as the pre-fetching can cause the DMA coherency issue, thus CPU get the stale data.

Obviously the block number is not power-of-2. But all MTD driver assumes the page per block and block per plane must be a power of 2 number. So the last 40 blocks in each plane must be truncated.

* ENGR00325088 video: mxsfb: Disable LCDIF correctlyLiu Ying2015-04-29-5/+9
| | | | | | | | | | | | | | | | | | | | | Let's use the i.MX common miscellaneous reset API to reset the LCDIF block so that we may eliminate a random hang issue at the arch_preboot_os() stage when we disable the LCDIF. This patch also waits for a VSYNC interrupt to guarantee the reset is done at the VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?) and helps the LCDIF work normally at the kernel stage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add EPDC splash screen feature for MX6SL EVK, and MX6DL SABRESD board. - Currently, splash screen consists of a simple black border around a white screen. Done this way to save in memory footprint. - EPDC splash screen is disabled by default in the config file for MX6DL_SABRESD and MX6SL_EVK. If left enabled, the U-Boot image will not boot correctly (hang), since some additional content on the boot device (waveform file) is required for EPDC splash to work correctly.

| * | mtd: vf610_nfc: specify transfer size before each transferStefan Agner2015-03-30-8/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Testing showed, that commands like STATUS made the buffer dirty when executed with NFC_SECSZ set to the page size. It looks like the controller transfers bogus data when this register is configured. When setting it to 0, the buffer does not get altered while the status command still seems to work flawless.

| * | mtd: vf610_nfc: mark page as dirty on block eraseStefan Agner2015-03-30-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver tries to re-use the page buffer by storing the page number of the current page in the buffer. The page is only read if the requested page number is not currently in the buffer. When a block is erased, the page number is marked as invalid if the erased page equals the one currently in the cache. However, since a erase block consists of multiple pages, also other page numbers could be affected. The commands to reproduce this issue (on a written page): > nand dump 0x800 > nand erase 0x0 0x20000 > nand dump 0x800 The second nand dump command returns the data from the buffer, while in fact the page is erased (0xff). Avoid the hassle to calculate whether the page is affected or not, but set the page buffer unconditionally to invalid instead. Signed-off-by: Stefan Agner <stefan@agner.ch>
| * | nand: yaffs: Remove the "nand write.yaffs" commandPeter Tyser2015-03-30-65/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This command is only enabled by one board, complicates the NAND code, and doesn't appear to have been functioning properly for several years. If there are no bad blocks in the NAND region being written nand_write_skip_bad() will take the shortcut of calling nand_write() which bypasses the special yaffs handling. This causes invalid YAFFS data to be written. See http://lists.denx.de/pipermail/u-boot/2011-September/102830.html for an example and a potential workaround. U-Boot still retains the ability to mount and access YAFFS partitions via CONFIG_YAFFS2. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
| * | nand: Remove CONFIG_MTD_NAND_VERIFY_WRITEPeter Tyser2015-03-30-248/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | The CONFIG_MTD_NAND_VERIFY_WRITE has been removed from Linux for some time and a more generic method of NAND verification now exists in U-Boot.
