The MX28 multi-layer AHB bus can be too slow and trigger the FEC DMA too early, before all the data hit the DRAM. This patch ensures the data are written in the RAM before the DMA starts. Please see the comment in the patch for full details. This patch was produced with an amazing help from Albert Aribaud, who pointed out it can possibly be such a bus synchronisation issue.

Remove incorrectly called and duplicate flush_dcache_range() call from fec_mxc driver. The call is not needed, since the caches are already flushed in fec_tbd_init(), moreover the second argument should be the ending address, not size. Signed-off-by:

Create a README.mxs file that contains instructions on how to use U-boot for both MX23 and MX28. As boot from NAND has only been tested on mx28, make it clear that it only applies to MX28. While at it, do some small cleanups for the sake of consistency: - Use "MX28" instead of "i.MX28" - Use "section" instead of "chapter" when referring to specific parts of the reference manual chapters.

The spi clock divisor is of the form x * (2**y), or x << y, where x is 1 to 16, and y is 0 to 15. Note the similarity with floating point numbers. Convert the desired divisor to the smallest number which is >= desired divisor, and can be represented in this form. The previous algorithm chose a divisor which could be almost twice as large as needed. Signed-off-by:

Fix two issues with the calculation of pre_div and post_div: 1. pre_div: While the calculation of pre_div looks correct, to set the CONREG[15-12] bits pre_div needs to be decremented by 1: The i.MX 6Dual/6Quad Applications Processor Reference Manual (IMX6DQRM Rev. 0, 11/2012) states: CONREG[15-12]: PRE_DIVIDER 0000 Divide by 1 0001 Divide by 2 0010 Divide by 3 ... 1101 Divide by 14 1110 Divide by 15 1111 Divide by 16 I.e. if we want to divide by 2, we have to write 1 to CONREG[15-12]. 2. In case the post divider becomes necessary, pre_div will be divided by 16. So set pre_div to 16, too. And not 15. Both issues above are tested using the following examples: clk_src = 60000000 (60MHz, default i.MX6 ECSPI clock) a) max_hz == 23000000 (23MHz, max i.MX6 ECSPI read clock) -> pre_div = 3 (divide by 3 => CONREG[15-12] == 2) -> post_div = 0 (divide by 1 => CONREG[11- 8] == 0) => 60MHz / 3 = 20MHz SPI clock b) max_hz == 2000000 (2MHz) -> pre_div = 16 (divide by 16 => CONREG[15-12] == 15) -> post_div = 1 (divide by 2 => CONREG[11- 8] == 1) => 60MHz / 32 = 1.875MHz SPI clock c) max_hz == 1000000 (1MHz) -> pre_div = 16 (divide by 16 => CONREG[15-12] == 15) -> post_div = 2 (divide by 4 => CONREG[11- 8] == 2) => 60MHz / 64 = 937.5kHz SPI clock d) max_hz == 500000 (500kHz) -> pre_div = 16 (divide by 16 => CONREG[15-12] == 15) -> post_div = 3 (divide by 8 => CONREG[11- 8] == 3) => 60MHz / 128 = 468.75kHz SPI clock Signed-off-by: -

When running the "save" command several times on a mx6qsabresd we see: U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed U-Boot > save Saving Environment to MMC... Writing to MMC(1)... done U-Boot > save Saving Environment to MMC... MMC partition switch failed This issue is caused by the incorrect usage of CONFIG_SYS_MMC_ENV_PART. CONFIG_SYS_MMC_ENV_PART should be used to specify the mmc partition that stores the environment variables. On some imx boards it is been incorrectly used to pass the partition of kernel and dtb files for the 'mmcpart' script variable. Remove the CONFIG_SYS_MMC_ENV_PART usage and configure the 'mmcpart' variable directly. Reported-by:

The number of gpio signal is packed inside CONFIG_SF_DEFAULT_CS macro (shifted and or'ed with chip select), so it's incorrect to pass that macro directly as an argument to gpio_direction_output() call. Also, SPI driver sets the direction and initial value of a gpio, used as a chip select signal, before any actual activity happens on the bus. So, it is safe to just remove the gpio_direction_output call, that works incorrectly, thus making no effect, anyway. Signed-off-by:

When the mx6slevk board support was added in U-boot there was no device tree support for mx6sl, so only a FSL 3.0.35 was tested at that time.
