This is next version patch series for -
http://u-boot.10912.n7.nabble.com/PATCH-0-5-sf-Add-support-to-access-dual-flash-memory-td160223.html
"nr_flash" support look likes how many no.of flashes can be connected
to a controller from a given chipselect. Usually from every controller
we can connect single flash with a single chipselect line and current
sf framework support too. but there are some hw logics(ex: xilinx zynq qspi)
describes two/dual memories are connected with a single chipselect line from
a controller.
This code nothing harm to existing sf with single flash as newly added
code is moved onto CONFIG_SF_NR_FLASH config option.
Changes for v2:
- rebase to current spi tree
- "option" variable on spi_slave so-that controller driver can specify
which they use
- Unify common code
