0f7210b0ae mtd: fix some unallocated and NULL pointer issues. rwb->wrflush and rwb->wrmaxblocks in rwbuffer could get unallocated values from ftl_initialize() in some configurations. Also fixes related assert: 
up_assert: Assertion failed at file:rwbuffer.c line: 643

that can happen with the following configuration:

  CONFIG_FTL_WRITEBUFFER=y
  CONFIG_DRVR_WRITEBUFFER=y
  # CONFIG_FS_WRITABLE is not set

These problems are caused by CONFIG variable differences between the buffer layers. TODO: This is not a perfect solution. readahead support has similar issues.

a10735b50d mtd/progmem: fix incorrect target address calculation 
progmem_read/write() is incorrectly calculating the target address,
expecting the offset argument is given in a block number. This is
completely wrong and as a result invalid flash region is accessed.
Byte-oriented read/write interfaces of mtd device accept the
target address in a byte offset, not a block number.

74777499bc alter the notion of 'blocksize' to be equivalent to 'flash write page size' in order to align with assumptions in the smartfs driver (at least, maybe other things do as well). 
Correct a bug that was previously masked by having blocksize=eraseblocksize which would cause buffer overflows and delicious hardfaults.
Trivial spelling changes in comments, etc.

0d41a1cd42 Before accessing the sst26 flash, the "Global Unlock" command must me executed, which I do in the sst26 driver. 
BUT. re-reading the datasheet, the WREN instruction is required to enable the execution of this command. This was not done.

I have no idea how the driver currently works except by chance. The writes
should never happen at all, the flash is half-enabled!
