mtd: sf: Add support AT26DF081A chip

2015-10-11T11:13:06Z

AT26DF081A is the spi flash type of TWR-MEM(SCH-26248) card. We can access the flash through DSPI2 on LS1021ATWR board. Signed-off-by: Yuan Yao Reviewed-by: Jagan Teki

of: clean up OF_CONTROL ifdef conditionals

2015-08-18T17:46:05Z

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

sf: ops: Add spi_flash_copy_mmap function

2015-08-17T17:59:14Z

When doing a memory mapped copy we may have DMA available and thus need to have this copy abstracted so that the driver can do it, rather than a simple memcpy. Signed-off-by: Tom Rini Signed-off-by: Vignesh R Reviewed-by: Jagan Teki

sf: Make 4K sector support configurable

2015-08-17T10:29:48Z

Make the support for 4K subpage I/O on a SPI NOR flash configurable. A board which requires the SPI NOR to be accessed in larger 32KiB or 64KiB pages can disable the 4K subpage support, but by default, the support for 4K subpage I/O is enabled. The functionality of this option is the same as CONFIG_MTD_SPI_NOR_USE_4K_SECTORS in Linux. This is extremely useful in case one uses UBI on a SPI NOR flash. UBI needs at least 15k EBs and can not work on a flash which uses 4k ones, so disabling the support for 4k subpages lets UBI work on such flash. Signed-off-by: Marek Vasut Reviewed-by: Jagan Teki
