* ARM: prevent misaligned array initsAlbert ARIBAUD2012-10-15-1/+5
| | | | | | | | | | | | | | Under option -munaligned-access, gcc can perform local char or 16-bit array initializations using misaligned native accesses which will throw a data abort exception. Fix files where these array initializations were unneeded, and for files known to contain such initializations, enforce gcc option -mno-unaligned-access.

* env: fix crash using default -f -aGerlando Falauto2012-10-05-0/+3
| | | | | | | | | | | env default -a -f calls env_check_apply on all existing environment variables with a NULL value for "newval" as a way of cleaning up. This causes string manipulation functions to crash on most architectures. So replace a NULL argument with an empty string.

| * OMAP: networking support for SPLIlya Yanok2012-10-01-2/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for networking in SPL. Some devices are capable of loading SPL via network so it makes sense to load the main U-Boot binary via network too. This patch tries to use existing network code as much as possible. Unfortunately, it depends on environment which in turn depends on other code so SPL size is increased significantly. No effort was done to decouple network code and environment so far.

| * PXE: FDT: Add support for fdt in PXEChander Kashyap2012-09-27-3/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now DT support is becoming common for all new SoC's. Hence it is better to have option for getting specific FDT from the remote server. This patch adds support for new label i.e. 'fdt'. This will allow to retrieve 'fdt blob' from the remote server. This patch take care for the following scenarios. The usage of fdt is optional. The 'fdt blob' can be retrieved from tftp or can be available locally or can be absent. If 'fdt_addr_r' environment variable is set and 'fdt' label is defined retrieve 'fdt blob' from tftp. 'fdt_addr_r' is then passed along bootm command. If 'fdt_addr' is set and 'fdt blob' is not retrieved from the tftp pass 'fdt_addr' to bootm command. In this case 'fdt blob' will be available at 'fdt_addr'. If 'fdt_addr' is not set and 'fdt blob' is not retrieve from tftp pass NULL to boot command. In this case 'fdt blob' is not required and absent.

| * net: Improve the speed of netconsoleJoe Hershberger2012-09-24-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously u-boot would initialize the network interface for every network operation and then shut it down again. This makes sense for most operations where the network in not known to be needed soon after the operation is complete. In the case of netconsole, it will use the network for every interaction with the shell or every printf. This means that the network is being reinitialized very often. On many devices, this intialization is very slow. This patch checks for consecutive netconsole actions and leaves the ethernet hardware initialized between them. It will still behave the same old way for all other network operations and any time another network operation happens between netconsole operations.

| | | | | | | | | | | | | | | | | | | | | | | | First, remove the puts from the case where we don't have an mkimage header as this is somewhat common and intentional for no-arg target images. Second, rework the final switch statement in board_init_r to, in the case of !CONFIG_SPL_OS_BOOT be only about doing debug prints about if we know what the magic is or not (the CONFIG_SPL_OS_BOOT case is unchanged). Then we call jump_to_image_no_args(). This gives us the same behavior as before but with slightly smaller code. Signed-off-by: Tom Rini <trini@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some system (e.g. powerpc), the load-address and entry-point is located at address 0. So the current approach to load the image (payload) including the header to the address "load-address - 64" can't work here. This patch adds an flag to skip this copying including header to the SPL framework. By setting SPL_COPY_PAYLOAD_ONLY, only the playload will be copied. This will be used by the SPL NOR flash driver on powerpc. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Tom Rini <trini@ti.com>

On MPC5xxx we need to make sure to only use the standard memcpy() implementation and not the MPC5xxx specific one. As the MPC5xxx version has some complexity which is not needed for this SPL booting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer, clear the BSS and call board_init_r. We mark this as weak as some platforms may need to perform additional initalization at this point. We provide a gd that we know will be in a usable location, once the BSS has been cleared to help with this as well. Finally, we no longer call relocate_code so remove that from the armv7 version.

We move the spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave the NAND one in-place as we plan to replace it later in this series. We use common/spl to avoid linker problems with respect to merging constant strings in objects. Otherwise all strings in common/ will be linked in and kept which grows SPL in size too much.

This way, users don't need to specify an explicit partition in their commands. b) Make use of get_device(). c) Add parameter to indicate whether returning a whole device is acceptable, or whether a partition is mandatory. d) Make error-checking of the user's device-/partition-specification more complete. In particular, if strtoul() doesn't convert all characters, it's an error rather than just ignored. The resultant device/partition returned by the function will be as follows, based on whether the disk has a partition table (ptable) or not, and whether the calling command allows the whole device to be returned or not. (D and P are integers, P >= 1) D D: No ptable: !allow_whole_dev: error allow_whole_dev: device D ptable: device D partition 1 D:0 !allow_whole_dev: error allow_whole_dev: device D D:P No ptable: error ptable: device D partition P D:auto No ptable: !allow_whole_dev: error allow_whole_dev: device D ptable: first partition in device D with bootable flag set.
