* pxe: implement fdtdir extlinux.conf tagStephen Warren2014-02-04-6/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | People who write (or scripts that auto-generate) extlinux.conf don't want to know about HW-specific information such as FDT filenames. Create a new extlinux.conf tag "fdtdir" that specifies only the directory where FDT files are located, and defer all knowledge of the filename to U-Boot. The algorithm implemented is: ========== if $fdt_addr_r is set: if "fdt" tag was specified in extlinux.conf: load the FDT from the filename in the tag else if "fdtdir" tag was specified in extlinux.conf: if "fdtfile" is set in the environment: load the FDT from filename in "$fdtfile" else: load the FDT from some automatically generated filename if no FDT file was loaded, and $fdtaddr is set: # This indicates an FDT packaged with firmware use the FDT at $fdtaddr ========== A small part of an example /boot/extlinux.conf might be: ========== LABEL primary LINUX zImage FDTDIR ./ LABEL failsafe LINUX bkp/zImage FDTDIR bkp/ ========== ... with /boot/tegra20-seaboard.dtb or /boot/bkp/tegra20-seaboard.dtb being loaded by the sysboot/pxe code.

* pxe: support "devicetree" tagStephen Warren2014-02-04-0/+1
| | | | | | | | | The specification for extlinux.conf[1] states that "fdt" is an alias for "devicetree". To date, U-Boot only implements "fdt". Rectify that. [1] http://freedesktop.org/wiki/Specifications/BootLoaderSpec/ Signed-off-by: Stephen Warren <swarren@nvidia.com>
* 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.

* fdt_support.c: Correct linux,initrd-start/end settingTom Rini2014-01-20-2/+2
| | | | | | | | | | | The change to add 64bit initrd support broke 32bit initrd support as it always set 64bits worth of data into the properties, even on 32bit systems. The fix is to use addr_cell_len (which already says how much data is in 'tmp') to set the property, rather than always setting 8. Thanks to Stephen Warren for pointing out the fix here.

* | 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.
