This converts the following to Kconfig:
  CONFIG_SF_DEFAULT_BUS
  CONFIG_SF_DEFAULT_CS
  CONFIG_SF_DEFAULT_MODE
  CONFIG_SF_DEFAULT_SPEED

I use moveconfig script and then manual check on generated u-boot.cfg
to solve the remaining issue.

MTD: mxs_nand_spl: Redo the way nand_init initializes 2019-03-13T08:14:35+00:00 Adam Ford aford173@gmail.com 2019-02-18T23:58:17+00:00 d46d27d3b6558904b8fb44e90393f11c54ef3363 Currently the spl system calls nand_init which does nothing. It isn't until an attempt to load from NAND that it gets initialized. Subsequent attempts to load just skip the initialization because NAND is already initialized. This moves the contents of mxs_nand_init to nand_init. In the event of an error, it clears the number of nand chips found. Any attempts to use nand will check if there are nand chips available instead of actually doing the initialization at that time. If there are none, it will return an error to the higher level calls.

MTD: nand: mxs_nand: Allow driver to auto setup ECC in SPL 2019-02-15T11:42:13+00:00 Adam Ford aford173@gmail.com 2019-01-17T13:16:39+00:00 04568bd0b6d673a325eed76bd857a9cbd0c556bc The initialization of the NAND in SPL hard-coded ecc.bytes, ecc.size, and ecc.strength which may work for some NAND parts, but it not appropriate for others. With the pending patch "mxs_nand: Fix BCH read timeout error on boards requiring ECC" the driver can auto configure the ECC when these entries are blank.
