2014-01-08sandbox: block driver using host file/device as backing storeHenrik Nordström
Provide a way to use any host file or device as a block device in U-Boot. This can be used to provide filesystem access within U-Boot to an ext2 image file on the host, for example. The support is plumbed into the filesystem and partition interfaces. We don't want to print a message in the driver every time we find a missing device. Pass the information back to the caller where a message can be printed if desired.

2013-12-31mtd: onenand: Fix unaligned accessMarek Vasut
Fix unaligned access in OneNAND core. The problem is that the ffchars[] array is an array of "unsigned char", but in onenand_write_ops_nolock() can be passed to the memcpy_16() function. The memcpy_16() function will treat the buffer as an array of "unsigned short", thus triggering unaligned access if the compiler decided ffchars[] to be not aligned. I managed to trigger the problem with regular ELDK 5.4 GCC compiler.

2013-12-19spi: tegra: clear RDY bit prior to every transferYen Lin
The RDY bit indicates that a transfer is complete. This needs to be cleared by SW before every single HW transaction, rather than only at the start of each SW transaction (those being made up of n HW transactions). It seems that earlier HW may have cleared this bit autonomously when starting a new transfer, and hence this code was not needed in practice. However, this is generally a good idea in all cases. In Tegra124, the HW behaviour appears to have changed, and SW must explicitly clear this bit. Otherwise, SW will believe that transfers have completed when they have not, and may e.g. read stale data from the RX FIFO.

2013-12-17mtd: nand: omap: fix ecc ops assignment when changing eccNikita Kiryanov
If we change to software ecc and then back to hardware ecc, the nand ecc ops pointers are populated with incorrect function pointers. This is related to the way nand_scan_tail() handles assigning functions to ecc ops: If we are switching to software ecc/no ecc, it assigns default functions to the ecc ops pointers unconditionally, but if we are switching to hardware ecc, the default hardware ecc functions are assigned to ops pointers only if these pointers are NULL (so that drivers could set their own functions). In the case of omap_gpmc.c driver, when we switch to sw ecc, sw ecc functions are assigned to ecc ops by nand_scan_tail(), and when we later switch to hw ecc, the ecc ops pointers are not NULL, so nand_scan_tail() does not overwrite them with hw ecc functions. The result: sw ecc functions used to write hw ecc data. Clear the ecc ops pointers in omap_gpmc.c when switching ecc types, so that ops which were not assigned by the driver will get the correct default values from nand_scan_tail().

2013-12-17mtd: nand: omap: fix sw->hw->sw ecc switchNikita Kiryanov
When switching ecc mode, omap_select_ecc_scheme() assigns the appropriate values into the current nand chip's ecc.layout struct. This is done under the assumption that the struct exists only to store values, so it is OK to overwrite it, but there is at least one situation where this assumption is incorrect: When switching to 1 bit hamming code sw ecc, the job of assigning layout data is outsourced to nand_scan_tail(), which simply assigns into ecc.layout a pointer to an existing struct prefilled with the appropriate values. This struct doubles as both data and layout definition, and therefore shouldn't be overwritten, but on the next switch to hardware ecc, this is exactly what's going to happen. The next time the user switches to software ecc, they're going to get a messed up ecc layout. Prevent this and possible similar bugs by explicitly using the private-to-omap_gpmc.c omap_ecclayout struct when switching ecc mode.

2013-12-17mtd: nand: omap: fix HAM1_SW ecc using default value for ecc.sizeNikita Kiryanov
Commit "mtd: nand: omap: enable BCH ECC scheme using ELM for generic platform" (d016dc42cedbf6102e100fa9ecb58462edfb14f8) changed the way software ECC is configured, both during boot, and during ecc switch, in a way that is not backwards compatible with older systems: Older version of omap_gpmc.c always assigned ecc.size = 0 when configuring for software ecc, relying on nand_scan_tail() to select a default for ecc.size (256), while the new version of omap_gpmc.c assigns ecc.size = pagesize, which is likely to not be 256. Since 1 bit hamming sw ecc is only meant to be used by legacy devices, revert to the original behavior.

Writing zero into I2Ci.I2C_CNT register causes random I2C failures in OMAP3 based devices. This seems to be related to the following advisory which apears in multiple erratas for OMAP3 SoCs (OMAP35xx, DM37xx), as well as OMAP4430 TRM: Advisory: I2C Module Does Not Allow 0-Byte Data Requests Details: When configured as the master, the I2C module does not allow 0-byte data transfers. Note: Programming I2Ci.I2C_CNT[15:0]: DCOUNT = 0 will cause undefined behavior. Workaround(s): No workaround. Do not use 0-byte data requests. The writes in question are unnecessary from a functional point of view. Most of them are done after I/O has finished, and the only one that preceds I/O (in i2c_probe()) is also unnecessary because a stop bit is sent before actual data transmission takes place. Therefore, remove all writes that zero the cnt register.
