[U-Boot] [PATCH v2 00/11] SF: Migrate to Linux SPI NOR framework

U-Boot SPI NOR support (sf layer) is quite outdated as it does not
support 4 byte addressing opcodes, SFDP table parsing and different types of
quad mode enable sequences. Many newer flashes no longer support BANK
registers used by sf layer to a access >16MB space.
Also, many SPI controllers have special MMIO interfaces which provide
accelerated read/write access but require knowledge of flash parameters
to make use of it. Recent spi-mem layer provides a way to support such
flashes but sf layer isn't using that.
This patch series syncs SPI NOR framework from Linux v4.19. It also adds
spi-mem support on top.
So, we gain 4byte addressing support and SFDP support. This makes
migrating to U-Boot MTD framework easier.
Tested with few Spansion, micron and macronix flashes with TI's dra7xx,
k2g, am43xx EVMs. I dont have access to flashes from other vendors. So,
I would greatly appreciate testing on other platforms. Complete series
with dependencies here[1]
For clean build on some platforms, depends on CONFIG_SPI_FLASH migration
to defconfigs [2]

Simon, Stefan, Thanks for testing previous versions.
I haven't carried Tested-by's here as I have added back SPI_FLASH_BAR
support (but isn't enabled by default). Would be great if you could
retest this series.
I am hoping there won't be any major rework/changes after this round.
Change log:
Since v1:
Remove #ifindef __UBOOT__
Add back BAR support, but dont enable as default for all platform (see
10/11 for more details)
Enable SPI_FLASH_TINY on boards where there is SPL size constraint as
seen on travis ci builds.
Drop sf_mtd changes for now as it seems to cause issues.
v1: https://patchwork.ozlabs.org/cover/1012146/
Since RFC v2:
Fix issues reported by Simon Goldschmidt wrt 4 use of byte addressing opcode
Fix issues in compiling SFDP code
Re organize file names and Makefile to simply spi-nor-tiny inclusion
Remove SPI_FLASH_BAR and SF_DUAL_FLASH as these are no longer used
RFC v2: https://patchwork.ozlabs.org/cover/1007589/
Since RFC v1:
Add lightweight SPI flash stack for boards with SPL size constraints
Provide non DM version of spi-mem
Fix build issues on different platforms as reported by travis-ci on v1
RFC v1: https://patchwork.ozlabs.org/cover/1004689/
