| * common: lcd.c: fix data abort exception when try to access bmp headerPrzemyslaw Marczak2014-02-03-14/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | Changes: - le16_to_cpu() to get_unaligned_le16() - le32_to_cpu() to get_unaligned_le32() when access fields in struct bmp header. This changes avoids data abort exception caused by unaligned data access.

* board_r - fixup functions table after relocationAlexey Brodkin2014-01-27-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | This is only required for "PIC" relocation and doesn't apply to modern "PIE" relocation which does data relocation as well as code. "init_sequence_r" is just an array that consists of compile-time adresses of init functions. Since this is basically an array of integers (pointers to "void" to be more precise) it won't be modified during relocation - it will be just copied to new location as it is. As a consequence on execution after relocation "initcall_run_list" will be jumping to pre-relocation addresses. As long as we don't overwrite pre-relocation memory area init calls are executed correctly. But still it is dangerous because after relocation we don't expect initially used memory to stay untouched.

* | bootm: Reinstate special case for standalone imagesSimon Glass2014-01-14-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For standalone images, bootm had a special case where the OS boot function was NULL but did actually exist. It was just called manually. This was removed by commit 35fc84fa which checks for the non-existence of this function before the special case is examined. There is no obvious reason why standalone is handled with a special case. Adjust the code so that standalone has a normal OS boot function. We still need a special case for when the function returns, but at least we can avoid the main problem. This is intended to fix the reported: ERROR: booting os 'U-Boot' (17) is not supported but needs testing. Signed-off-by: Simon Glass <sjg@chromium.org>

During measurements at our lab we found that some cards implementing this feature having really strong driver strengts per default. This can lead to voltage peaks above the specification of the host on signal edges for data sent from a card to the host. Since availability of a given card type may be shorter than the time a certain hardware will be produced it is useful to have support for this command (Alternative would be changing termination resistors and adapting the driver strength of the host to the used card.) Following proposal for an implementation: - new field that reflects CSD field DSR_IMP in struct mmc - new field for design specific DSR value in struct mmc - board code can set DSR value in mmc struct just after registering an controller - mmc_startup sends the the stored DSR value before selecting a card, if DSR_IMP is set Additionally the mmc command is extended to make is possible to play around with different DSR values. The concept was tested on a i.MX53 based platform using a Micron eMMC card where the default DSR is 0x0400 (12mA) but in our design 0x0100 (0x0100) were enough. To use this feature for instance on a mx53loco one have to add a call to mmc_set_dsr() in board_mmc_init() after calling fsl_esdhc_initialize() for the eMMC.
