SPL from nand will print 'NAND' in boot_from_devices based on the image_loader name, remove the extra 'NAND ' in mxs_nand_spl driver. Original behaviour: ------------------- U-Boot SPL 2017.01-rc2-gf84dd8b (Jan 02 2017 - 22:24:19) Trying to boot from NANDNAND : 512 MiB After the fix: ------------- U-Boot SPL 2017.01-rc2-gf84dd8b-dirty (Jan 02 2017 - 23:17:00) Trying to boot from NAND: 512 MiB Cc: Tom Rini <trini@konsulko.com> Signed-off-by: Jagan Teki <jagan@openedev.com>
This reverts commit c56ae7519f141523ba1248b22b5b5169b21772fe. Once the 'Quad Enable' bit is cleared in their Enhanced Volatile Configuration Register (EVCR), Micron memories expect ALL commands to use the SPI 4-4-4 protocol. Commands using SPI 1-y-z protocols are no longer accepted. Within the reverted commit, the write_evcr() function is implemented using the spi_flash_write_common(), which is a shortcut for the [ spi_flash_cmd_write_enable(), spi_flash_cmd_write(), spi_flash_cmd_wait_ready() ] sequence. Since the internal state of the Micron memory has been changed when the spi_flash_cmd_write() function completes, the later call of the spi_flash_cmd_wait_ready() function fails. Indeed the SPI controller driver is not aware of the SPI protocol switch. Further patches will fix the support of Micron QSPI memories.

As long as the memory mapped size specifeid in the DT is the same or bigger than the device size, it will work. So do not force the sizes to be identical. Signed-off-by: Phil Edworthy <phil.edworthy@renesas.com> Reviewed-by: Jagan Teki <jagan@openedev.com>
In spi_flash_scan, 'ret' is initialled to -1, but 'ret' is not always used to store a return value, in that case, even when the function succeed, an error (-1) will be returned. Lets just return 0 if we hit the end of the function. Signed-off-by: Fabien Parent <fparent@baylibre.com> Reviewed-by: Jagan Teki <jagan@openedev.com>
It is useful to name each method so that we can print out this name when using the method. Currently this happens using a separate function. In preparation for unifying this, add a name to each method. The name is only available if we have libcommon support (i.e can use printf()). Signed-off-by: Simon Glass <sjg@chromium.org>
The indentation is misleading here and suggests that the write command will be only executed in the else clause. It seems like this is not intended, so fix the indentation to avoid both compiler warnings and puzzled readers. Pointed out by GCC 6.2's -Wmisleading-indentation warning.
