c08293893a kernel: add support for limiting 4K erase sector support based on flash chip size
Some targets need 4K sectors for small flash chips (e.g. some
routerboards, where the entire chip is just one "erase block"), whereas
on other devices 4K sectors lead to horrible flash erase/write
performance.

Set the default limit in the generic kernel configuration to 4 MiB to
ensure that all new platforms don't use 4K sectors for bigger flash
chips. On all existing targets use 16 MiB for now to avoid regressions.
They will be changed individually in follow-up commits.

68e7a2a0b7 kernel: disable CONFIG_SG_POOL by default
CONFIG_SG_POOL symbol is selected only by CONFIG_SCSI, since the last
one is disabled by default then disable CONFIG_SG_POOL by default too.
And explicitly enable it only for platforms that use CONFIG_SCSI.

52c17bff3c pistachio: add 4.9 kernel support
This adds kernel support for the Pistachio SoC and the Marduk (Ci40)
board which uses it.

Much of the code for Pistachio has been upstreamed however some
patches are still required to boot from the Marduk board:
 * spi bug fixes
 * dma bug fixes
 * pistachio internal clock tree bug fixes
 * spi-nand implementation
 * dts based mtd device naming scheme
 * dts backports and bug fixes
