2012-09-05mmc: Fix version check for clock API in sdhci driverJoe Hershberger
When setting up the clocks in the sdhci driver, the "spec version" must be masked off. Otherwise any time the vendor version is not 0, the check will allways assume the interface is version 3. This breaks when the interface is actually version 1 or 2. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

2012-09-05tegra: put eMMC environment into the boot sectorsStephen Warren
When I set up Tegra's config files to put the environment into eMMC, I assumed that CONFIG_ENV_OFFSET was a linearized address relative to the start of the eMMC device, and spanning HW partitions boot0, boot1, general* and the user area in order. However, it turns out that the offset is actually relative to the beginning of the user area. Hence, the environment block ended up in a different location to expected and documented. Set CONFIG_SYS_MMC_ENV_PART=2 (boot1) to solve this, and adjust CONFIG_ENV_OFFSET to be relative to the start of boot1, not the entire eMMC.

2012-09-05env_mmc: allow environment to be in an eMMC partitionStephen Warren
eMMC devices may have hardware-level partitions: 2 boot partitions, up to 4 general partitions, plus the user area. This change introduces optional config variable CONFIG_SYS_MMC_ENV_PART to indicate which partition the environment should be stored in: 0=user, 1=boot0, 2=boot1, 4..7=general0..3. This allows the environment to be kept out of the user area, which simplifies the management of OS-/user-level (MBR/GPT) partitions within the user area.

2012-09-05mmc: detect boot sectors using EXT_CSD_BOOT_MULT tooStephen Warren
Some eMMC devices contain boot partitions, but do not set the PART_SUPPORT bit in EXT_CSD_PARTITIONING_SUPPORT. Allow partition selection on such devices, by enabling partition switching when EXT_CSD_BOOT_MULT is set. Note that the Linux kernel enables access to boot partitions solely based on the value of EXT_CSD_BOOT_MULT; EXT_CSD_PARTITIONING_SUPPORT only influences access to "general" partitions. eMMC devices affected by this issue exist on various NVIDIA Tegra platforms (and presumably many others too), such as Harmony (plug-in eMMC), Seaboard, Springbank, and Whistler (plug-in eMMC).

2012-09-05mmc: fix capacity calculation when EXT_CSD_SEC_CNT is usedYoshihiro Shimoda
Since the type of "ext_csd" was array of char, the following calculation might fail when the value of ext_csd[EXT_CSD_SEC_CNT] was minus. capacity = ext_csd[EXT_CSD_SEC_CNT] << 0 | ext_csd[EXT_CSD_SEC_CNT + 1] << 8 | ext_csd[EXT_CSD_SEC_CNT + 2] << 16 | ext_csd[EXT_CSD_SEC_CNT + 3] << 24; So, this patch changes the type of "ext_csd" to array of u8.

2012-09-02powerpc: re-add bi_ip_addr to bd_t structAnatolij Gustschin
Since commit 50a47d0523e8efebe912bef539a77ffd42116451 (net: punt bd->bi_ip_addr) booting old 2.4.x ppc kernels is broken due to changed offsets of the fields in struct bd_t. Offsets of the fields after removed bi_ip_addr are wrong, causing wrong bus clocks and console baudrate configurations and various other issues. Re-add the bi_ip_addr field to preserve backward compatibility with older ppc kernels. Setting bi_ip_addr in board.c is not really needed, grepping in the 2.4 linux tree shows that bi_ip_addr is not accessed there. Adding bi_ip_addr to struct bd_t for other arches isn't needed it seems. bd_t is not used by other arches in the 2.4 linux tree.

When the year digit data overflows from 99 to 00, * this bit is set. By presetting it to 0 while still in the * 20th century, it will be set in year 2000, ... * There seems no reliable way to know how the system use this * bit. So let's do it heuristically, assuming we are live in * 1970...2069. */ As U-Boot's PCF8563 driver does not say it is supposed to support the RTC8564, make this driver compatible with Linux's by giving the opposite meaning to the century bit.
