[U-Boot] [PATCH] mx28evk: Convert to mxs_adjust_memory_params()
by Fabio Estevam 04 Sep '12

04 Sep '12

Recent conversion from mx28_adjust_memory_params to mxs_adjust_memory_params missed to update mx28evk, which caused the board not to boot. Apply the conversion so that the board can boot again.

[U-Boot] [PATCH] M28: Fix the use of gpmi-nand in mtdparts
by Marek Vasut 04 Sep '12

04 Sep '12

The mtd name of the NAND in Linux is "gpmi-nand", not "gpmi-nand.0" as it would be expected, since the controller doesn't support multiple NANDs attached to it as of now. Rectify this flub by adjusting default mtdparts.

[U-Boot] [PATCH] mtest: Disable dcache during test
by Benoît Thébaudeau 04 Sep '12

04 Sep '12

mtest is supposed to test many types of memory accesses in many different conditions. If dcache is enabled, memory accesses are likely bursts, and some memory accesses are simply skipped. Hence, dcache should be disabled during mtest operation so that what mtest actually tests is not masked by dcache.

[U-Boot] trouble with mmc on origen
by John Rigby 04 Sep '12

04 Sep '12

Jaehoon, I get timeouts on multiblock mmc reads with v2012.07 u-boot. I did a bisect and found that it is broken back to 442d55685e1e2310d546044a6519ae73e4ba348a mmc: support the sdhci instead of s5p_mmc for samsung-soc and 236bfecff8091356d81e79da3281b9e4af967468 mmc: add the quirk to use the sdhci for samsung-soc That second commit seems to adds two new quirks SDHCI_QUIRK_NO_HISPD_BIT and SDHCI_QUIRK_BROKEN_VOLTAGE but I don't see any board using these so perhaps these need to be enabled for origen? Thanks, --john
