Tested on Xilinx Zynq-7000 FPGA board.
Changes since v8:
- Took another patch from Pratyush's series
- Define spansion_quad_enable_volatile() under CONFIG_SPI_FLASH_SPANSION
Changes since v7:
- Fixed return type of s25hx_t_erase_non_uniform() to 'int'
Changes since v6:
- Took some patches from Pratyush's series
- Removed USE_CLSR flag from S25HL02GT and S25HS02GT
- Defined SPINOR_OP_EX4B_CYPRESS and use it

- Remove spansion_quad_enable_volatile() from tiny
- Fixed some other minor issues
Changes since v5:
- Removed 256Mb and 4Gb parts support
- Fixed register offset issue in spansion_quad_enable_volatile()
- Added spi_nor_default_ready() and moved existing code into it
- Separated spansion_sr_read() to new patch
- Renamed spansion_overlaid_erase() to spansion_non_uniform_erase() and
changed the implementation to issue the proper erase command based on
the address
- Added s25hx_t_erase_non_uniform()
- Changed mtd.writesize and mtd.flags in s25hx_t_setup()
- Fixed page size and erase size issues in s25hx_t_post_bfpt_fixup()
Changes since v4:
- Added Read/Write Any Register support

- Added S25HL02GT/S25HL04GT/S25HS02GT/S25HS04GT support
Changes since v3:
- Split into multiple patches
Changes since v2:
- Fixed typo in comment for spansion_overlaid_erase()
- Fixed expressions for addr and len check in spansion_overlaid_erase()
- Added device ID check to make the changes effective for S25 only
- Added nor->setup() and fixup hooks based on the following patches
