ffdb20bea1 sandbox: spi: Add new SPI flash driver
This adds a SPI flash driver which simulates SPI flash clients.
Currently supports the bare min that U-Boot requires: you can
probe, read, erase, and write.  Should be easy to extend to make
it behave more exactly like a real SPI flash, but this is good
enough to merge now.

sjg@chromium.org added a README and tidied up code a little.

7aa6c455c3 powerpc: spiflash:Add corenet devices support in eSPI SPL
Existing eSPI SPL framework assumes booting from spi-image
with boot_format header which contains final u-boot Image
offset and size. No such header is present in case of
corenet devices like T1040 as corenet deivces use PBI-RCW
based intialization.

So, for corenet deives, SPL bootloader use values provided
at compilation time. These values can be defined in board
specific config file.

004f15b600 sf: Add memory mapped read support
Qspi controller can have a memory mapped port which can be used for
data read. Added support to enable memory mapped port read.

This patch enables the following:
- It enables exchange of memory map address between mtd and qspi
through the introduction of "memory_map" flag.
- Add support to communicate to the driver that memory mapped
 transfer is to be started through introduction of new flags like
"SPI_XFER_MEM_MAP" and "SPI_XFER_MEM_MAP_END".

This will enable the spi controller to do memory mapped configurations
if required.

fdf8529afc powerpc : spi flash : Support to start from eSPI with SPL
This patch introduces SPL to enable a loader stub that being loaded by
the code from the internal on-chip ROM. It loads the final uboot image
into DDR, then jump to it to begin execution.

The SPL's size is sizeable, the maximum size must not exceed the size of L2
SRAM. It initializes the DDR through SPD code, and copys final uboot image
to DDR. So there are two stage uboot images:
	* spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that
	ddr spd code can get the interleaving mode setting in env. It loads
	final uboot image from offset 96KB.
	* final uboot image, size is variable depends on the functions enabled.

e3ff9d51ec sf: Update sf to support all sizes of flashes
Updated the spi_flash framework to handle all sizes of flashes
using bank/extd addr reg facility

The current implementation in spi_flash supports 3-byte address mode
due to this up to 16Mbytes amount of flash is able to access for those
flashes which has an actual size of > 16MB.

As most of the flashes introduces a bank/extd address registers
for accessing the flashes in 16Mbytes of banks if the flash size
is > 16Mbytes, this new scheme will add the bank selection feature
for performing write/erase operations on all flashes.

This parameter can be used by spi flash commands that need to round

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

d9596ffbdc sf: stmicro: dont send 4 bytes when reading status register
I can't find anywhere in the datasheet that says the status register needs
3 dummy bytes sent to it before being able to read back the first real
result.  Tests on a Blackfin board show that after writing the opcode, the
status register starts coming back immediately.  So only write out the
read status register opcode before polling the result.

1abe365ffc sf: set common timeouts in seconds, not milliseconds
Since timeouts are only hit when there is a problem in the system, we
don't want to prematurely timeout on a functioning setup.  Thus having
low timeouts (in milliseconds) doesn't gain us anything in the production
case, but rather increases likely hood of causing problems where none
otherwise exist.

0dcdbb172c sf: always read 5 bytes for the idcode
Some SPI flash drivers like to have extended id information available
(like the spansion flash), so rather than making it re-issue the ID cmd
to get at the last 2 bytes, have the common code read 5 bytes rather than
just 3.  This also matches the Linux behavior where it always reads 5 id
bytes from all flashes.

9726ba4aba sf: stmicro: drop redundant id read
The common SPI flash code reads the idcode and passes it down to the SPI
flash driver, so there is no need to read it again ourselves.

68f8718df2 spi flash: fix crash due to spi flash miscommunication
Higher spi flash layers expect to be given back a pointer that was
malloced so that it can free the result, but the lower layers return
a pointer that is in the middle of the malloced memory. Reorder the
members of the lower spi structures so that things work out.
