spi, sf: Use offset and size in sf cmd from mtdpartition
With this patch, it is possible to get the offset and size information
from the mtdpartiton setting in "mtdparts", similiar to the
"nand" commandos.
=> sf
sf - SPI flash sub-system
Usage:
sf probe [[bus:]cs] [hz] [mode] - init flash device on given SPI bus
and chip select
sf read addr offset|partition len - read `len' bytes starting at
`offset' to memory at `addr'
sf write addr offset|partition len - write `len' bytes from memory
at `addr' to flash at `offset'
sf erase offset|partition [+]len - erase `len' bytes from `offset'
`+len' round up `len' to block size
sf update addr offset|partition len - erase and write `len' bytes from memory
at `addr' to flash at `offset'
=>
for example "env" is defined in mtdparts:
=> sf read 13000000 env
device 0 offset 0xd0000, size 0x10000
SF: 65536 bytes @ 0xd0000 Read: OK
zynq-uboot> mtdparts add nor0 0x10000@0x0 env
zynq-uboot> sf erase env 0x10000

zynq-uboot> sf write 0x100 env

Move common functions from cmd_nand.c (for calculating offset
and size from cmdline paramter) to common place, so they could
used from other commands which use mtd partitions.

Note (From Jagan): For testing raw mtd parition erase/read/write operations
using cmd_sf, sf_mtd should be required to register the spi flash device to
MTD layer but the sf_mtd_info ops were not required until and unless if we
use any flash filesystem layer say for example UBI. Due to this the foot-print
got increased ~290bytes in non-UBI case here that should be acceptible.

This allows using only one of either raw or fs mode for SPL mmc boot, without
the need to have provisions for the other. In particular, a device may have
U-Boot installed on a file system on the mmc, without ever needing to read

tools/kwbimage.c: Correct header size for SPI boot
If defined, the macro CONFIG_SYS_SPI_U_BOOT_OFFS allows a board
to specify the offset of the payload image into the kwb image
file. This value was being used to locate the image, but was not
used in the "header size" field of the main header. Move the
use of this macro into the function that returns the header size
so that the same value is used in all places.

ahci: extend data io wait to 10s
The AHCI driver currently waits 5s before timing out when sending a
data command to a drive. Some drives take upwards of 8s to respond to
the initial data command while they're spinning up. Increase the
data io timeout to 10s so that those drives can be found on initial
scsi scan.

ahci: support LBA48 data reads for 2+TB drives
Enable full 48-bit LBA48 data reads by passing the upper word of the

This allows uboot to load data from any arbitrary sector on a drive

The Calxeda Midway part has A15 cores, which do not have the Highbank

Enabling IO delay recalibration sequence for DRA7 EVM.

In addition to the regular mux configuration, certain pins of DRA7

delay characteristics cannot be used for the interface.
struct iodelay_cfg_entry is introduced for populating

For configuring manual mode, along with the normal pad

- Select MODESELECT field of each assocaited PAD.
CTRL_CORE_PAD_XXX[8]:MODESELECT = 1(Enable MANUAL_MODE macro along with mux)
- Populate A_DELAY, G_DELAY values that are specified in DATA MANUAL.

ARM: DRA7: Add support for IO delay configuration
On DRA7, in addition to the regular muxing of pins, an additional
hardware module called IODelay which is also expected to be
configured. This "IODelay" module has it's own register space that is
independent of the control module.
It is advocated strongly in TI's official documentation considering
the existing design of the DRA7 family of processors during mux or
IODelay recalibration, there is a potential for a significant glitch
which may cause functional impairment to certain hardware. It is
hence recommended to do muxing as part of IOdelay recalibration.
IODELAY recalibration sequence:
- Complete AVS voltage change on VDD_CORE_L
- Unlock IODLAY config registers.
- Perform IO delay calibration with predefined values.
- Isolate all the IOs
- Update the delay mechanism for each IO with new calibrated values.
- Configure PAD configuration registers
- De-isolate all the IOs.
- Relock IODELAY config registers.
