* fs/ext4: Support device block sizes != 512 bytesEgbert Eich2013-05-10-9/+4
| | | | | | | | | The 512 byte block size was hard coded in the ext4 file systems. Large harddisks today support bigger block sizes typically 4096 bytes. This patch removes this limitation. Signed-off-by: Egbert Eich <eich@suse.com>
* gpio: Add support for microblaze xilinx GPIOMichal Simek2013-05-09-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it. Add gpio driver and change Microblaze reset logic to be done via gpio subsystem. There are various configurations which Microblaze can have that's why gpio_alloc/gpio_alloc_dual(for dual channel) function has been introduced and gpio can be allocated dynamically. Adding several gpios IP is also possible and supported. For listing gpio configuration please use "gpio status" command This patch also remove one compilation warning: microblaze-generic.c: In function 'do_reset': microblaze-generic.c:38:47: warning: operation on '*1073741824u' may be undefined [-Wsequence-point] Signed-off-by: Michal Simek <michal.simek@xilinx.com>

| * mmc: Split device init to decouple OCR-polling delayChe-Liang Chiou2013-05-06-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of time that MMC driver spends on initializing a device is polling OCR (operation conditions register). To decouple this polling loop, device init is split into two parts: The first part fires the OCR query command, and the second part polls the result. So the caller is now no longer bound to the OCR-polling delay; he may fire the query, go somewhere and then come back later for the result. To use this, call mmc_set_preinit() on any device which needs this. This can save significant amounts of time on boot (e.g. 200ms) by hiding the MMC init time behind other init.

| * powerpc/85xx: set USB2 default mode to 'device' for (super)hydra boardsShaohui Xie2013-05-02-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Hydra and Superhydra (P3041DS, P5020DS, and P5040DS) boards have a second USB port that can be configured in either host, peripheral (aka device), or OTG (on-the-go) mode. When configured in host mode, if the port is connected to another USB host, damage to the board can occur. To avoid this, we change the default setting to peripheral mode. Ideally, we'd set it to OTG mode, but currently there is no OTG support for these boards. Setting the hwconfig variable will also update the device tree, and so Linux will configure the port for peripheral mode as well.

| * mpc5200: a3m071/a4m2k: Fix problem with increased global_data structStefan Roese2013-05-02-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The v2013.04 release has this patch set included: 5cb48582 "Add architecture-specific global data" With this, the global_data struct is now common and new variables have been added. Resulting in a bigger struct. Unfortunately the currently allocated 128 bytes are just a bit too small for this new struct. This patch now uses the automatically generated struct size instead to not run into this problem again. Please note that this problem might hit some other platforms which currently reserve a tight space of 128 bytes for the global_data struct! Signed-off-by: Stefan Roese <sr@denx.de>

Used to implement regex operations on environment variables. Code size is ~ 3.5 KiB on PPC. To enable this code, define the CONFIG_REGEX option in your board config file. Note: There are more recent versions of the SLRE library available at http://slre.googlecode.com ; unfortunately, the new code has a heavily reorked API which makes it less usable for our purposes: - the return code is strings, which are more difficult to process - we don't get any information any more which sub-string of the data was matched by the given regex - it is much more cumbersome to work with arbitrary expressions, where for example the number of substrings for capturing are not known at compile time Also, there does not seem to be any real changes or improvements of the functionality. Because of this, we deliberately stick with the older code. Note 2: the test code (built when SLRE_TEST is defined) was modified to allow for more extensive testing; now we can test the regexp matching on all lines on a text file (instead of the whole data in the file as a single block).

* sandbox: Provide a way to map from host RAM to U-Boot RAMSimon Glass2013-05-01-0/+5
| | | | | | | | | | | | | | | | | | | | | In many cases, pointers to memory are passed around, and these pointers refer to U-Boot memory, not host memory. This in itself is not a problem. However, in a few places, we cast that pointer back to a ulong (being a U-Boot memory address). It is possible to convert many of these cases to avoid this. However there are data structures (e.g. struct bootm_headers) which use pointers. We could with a lot of effort adjust the structs and all code that uses them to use ulong instead of pointers. This seems like an unacceptable cost, since our objective with sandbox is to minimise the impact on U-Boot code while maximising the features available to sandbox. Therefore, create a map_to_sysmem() function which converts from a pointer to a U-Boot address. This can be used sparingly when needed. Signed-off-by: Simon Glass <sjg@chromium.org>
