| | | | | | | | | | | | | | | | | | | | | When kb_fifo_start is 0, the index calculation yields -1 because C got the mod (%) operation arguably wrong.

FLASH_WRITE_BYTES is provided as part of EC_CMD_FLASH_INFO, so programs which query size this way will can take advantage of 64-byte writes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This works around a problem where columns are not tri-stated when calling select_column(COLUMN_ASSERT_ALL) with enable_scanning=0. Also removes polling for power button released; we can use the same task wait for that as we do for a keypress.
