2012-03-27[SCSI] ufshcd: UFS Host controller driverSantosh Yaraganavi7-0/+2614
This patch adds support for Universal Flash Storage(UFS) host controllers. The UFS host controller driver includes host controller initialization method. The Initialization process involves following steps: - Initiate UFS Host Controller initialization process by writing to Host controller enable register - Configure UFS Host controller registers with host memory space datastructure offsets. - Unipro link startup procedure - Check for connected device - Configure UFS host controller to process requests - Enable required interrupts - Configure interrupt aggregation [jejb: fix warnings in 32 bit compile] Signed-off-by: Santosh Yaraganavi <[email protected]> Signed-off-by: Vinayak Holikatti <[email protected]> Reviewed-by: Arnd Bergmann <[email protected]> Reviewed-by: Vishak G <[email protected]> Reviewed-by: Girish K S <[email protected]> Reviewed-by: Namjae Jeon <[email protected]> Signed-off-by: James Bottomley <[email protected]>

2012-03-26ACPICA: Sleep/Wake interfaces: optionally execute _GTS and _BFSLin Ming5-39/+63
Enhanced the sleep/wake interfaces to optionally execute the _GTS method (Going To Sleep), and the _BFS method (Back From Sleep). Windows apparently does not execute these methods, and therefore these methods are often untested. It has been seen on some systems where the execution of these methods causes errors and also prevents the machine from entering S5. It is therefore suggested that host operating systems do not execute these methods by default. In the future, perhaps these methods can be optionally executed based on the age of the system and/or what is the newest version of Windows that the BIOS asks for via _OSI.

2012-03-27mtd: docg3 add protection against concurrencyRobert Jarzmik2-11/+41
As docg3 is intolerant against reentrancy, especially because of its weird register access (ie. a register read is performed by a first register write), each access to the docg3 IO space must be locked. Lock the IO space with a mutex, shared by all chips on the same cascade, as they all share the same IO space.

2012-03-27mtd: docg3 increase write/erase timeoutRobert Jarzmik1-3/+3
After several tries with ubifs, it appears empirically that constructor provided figures for erase/write timeouts are underestimated.

2012-03-27mtd: docg3 fix inbound calculationsRobert Jarzmik1-12/+5
The last erase block was not accessible, as the out of bound check was incorrectly rejecting the last block. The read/write/erase offset checks were forbidding the usage of the last block, because of the calculation which was considering the byte after the last instead of the last byte.

With onfi a flash is organized into one or more logical units (LUNs). A logical unit (LUN) is the minimum unit that can independently execute commands and report status. Mtd does not exploit LUN, so make it see a big single flash where size is lun_size * number_of_lun. Without this patch MT29F8G08ADBDAH4 size is 512MiB instead of 1GiB.

2012-03-27mtd: nand/fsmc: Add DMA supportVipin Kumar1-5/+163
The fsmc_nand driver uses cpu to read/write onto the device. This is inefficient because of two reasons - the cpu gets locked on AHB bus while reading from NAND - the cpu is unnecessarily used when dma can do the job This patch adds the support for accessing the device through DMA Signed-off-by: Vipin Kumar <[email protected]> Reviewed-by: Viresh Kumar <[email protected]> Signed-off-by: Artem Bityutskiy <[email protected]> Signed-off-by: David Woodhouse <[email protected]>
2012-03-27mtd: nand/fsmc: Access the NAND device word by word whenever possibleVipin Kumar1-0/+55
The default way of accessing nand device is using the nand width. This means that 8bit devices are using u8 * and 16bit devices are accessed using u16 *. This results in a non-optimal performance since the FSMC is designed to translate the normal word accesses into device width based accesses. This patch implements read_buf and write_buf callbacks using word by word accesses.

2012-03-27mtd: nand/fsmc: Modify fsmc driver to accept nand timing parameters via platformVipin Kumar1-8/+33
FSMC controllers provide registers to program the required timing values for attached NAND device. The timing values used until now are relaxed and should work for all devices. Although, for read/write performance improvements, the fsmc nand driver should accept nand timings as a platform data and program the timing parameters into fsmc registers accordingly. This patch implements this modification. Additionally, it programs the default timing parameters if these are not passed via platform data.

2012-03-27mtd: nand/fsmc: Initialize the badblockbits to 7Vipin Kumar1-0/+1
Ideally, the block should have 0xff written on the bad block position. Any value other than 0xff implies a bad block. In practical situations, there can be bit flips in the oob area as well which means that a block with 0x7f being read at bad block position may imply a bad block but it is infact only a bit flip in the bad block byte. To resolve this problem, the block is marked as good if number of high bits is greater than or equal to badblockbits (initialized to 7) Signed-off-by: Vipin Kumar <[email protected]> Signed-off-by: Artem Bityutskiy <[email protected]> Signed-off-by: David Woodhouse <[email protected]>
2012-03-27mtd: nand/fsmc: Flip the bit only if the error index is < 4096Vipin Kumar1-1/+1
ECC can correct up to 8 bits in 512 bytes data + 13 bytes ecc. This means that the algorithm can correct a max of 8 bits in 4200 bits ie the error indices can be from 0 to 4199. Of these 0 to 4095 are for data and 4096 to 4199 for ecc. The driver flips the bit only if the index is <= 4096. This is a bug since the data bits are only from 0 to 4095.

2012-03-27mtd: nand/fsmc: Read only 512 + 13 bytes for 8bit NAND devicesVipin Kumar1-1/+3
The ECC logic of FSMC works on 512 bytes data + 13 bytes ECC to generate error indices of up to 8 incorrect bits. The FSMC driver reads 14 instead of 13 oob bytes to accommodate for 16 bit device as well. Unfortunately, the internal ecc state machine gets corrupted for 8 bit devices reading 512 + 14 bytes of data resulting in error indices not getting reported.
