* SPL: Add support for loading image from ram in SPL.Pavel Machek2012-09-27-0/+26

* SPL: Rework how we inform about un-headered imagesTom Rini2012-09-27-5/+2
| | | | | | | | | | | | 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>

* SPL: Enable use of custom defined U-Boot entry pointStefan Roese2012-09-27-1/+4
| | | | | | | | | By setting CONFIG_SYS_UBOOT_START boards can now use a different entry point for their U-Boot image. So the U-Boot entry point is not fixed to CONFIG_SYS_TEXT_BASE any more. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Tom Rini <trini@ti.com>

* SPL: Add option to skip copying of the mkimage headerStefan Roese2012-09-27-4/+20
| | | | | | | | | | | | | | | 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>
* SPL: Add NOR flash booting supportStefan Roese2012-09-27-0/+71
| | | | | | | | | | | | | SPL NOR flash booting support is quite simple. Only copying of the images is needed. 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.

* da850: Add README.da850Tom Rini2012-09-27-0/+68

It also documents how to write the u-boot.ais file to persistent storage (such as SPI), in some cases as well as how to write a recovery image.

* hawkboard: Update config file to work with common spl frameworkSughosh Ganu2012-09-27-1/+1
| | | | | | | | | | The common spl framework expects the u-boot payload size through CONFIG_SYS_MONITOR_LEN. Define the macro with the u-boot's size. With this change, CONFIG_SYS_NAND_U_BOOT_SIZE is no longer required. Delete the same. Signed-off-by: Tom Rini <trini@ti.com> Signed-off-by: Sughosh Ganu <urwithsughosh@gmail.com>

* SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linuxTom Rini2012-09-27-46/+98
| | | | | | | | | | | | | | 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. Next, both board_init_f and jump_to_image_linux are going to be inherently arch-specific, so move these versions to arch/arm/lib/spl.c Signed-off-by: Tom Rini <trini@ti.com>
* SPL: Move the omap SPL framework to common/splTom Rini2012-09-27-59/+138
| | | | | | | | | | | | | Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL framework, enable on all of the previously using boards. 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.

* ARM: SPL: Clean up spl.c / spl_nand.c slightlyTom Rini2012-09-27-16/+8
| | | | | | | | | | | | | - Remove includes we don't need - Switch some printf statements to puts - Convert some printf statements to debug, introduce new puts statements - In most cases saying just "No mkimage signature, assuming u-boot.bin" or similar is sufficient. This also means the non-DEBUG case doesn't need printf, in the core of SPL. - The other case here is that PLAIN_VERSION provided what we wanted already, so just use it.

* FAT: Make it possible to read from any file positionBenoît Thébaudeau2012-09-26-38/+105
| | | | | | | | | | | | | | | When storage devices contain files larger than the embedded RAM, it is useful to be able to read these files by chunks, e.g. for a software update to the embedded NAND Flash from an external storage device (USB stick, SD card, etc.). Hence, this patch makes it possible by adding a new FAT API to read files from a given position. This patch also adds this feature to the fatload command.

| * video/powerpc: don't touch DIU registers that we don't needTimur Tabi2012-09-21-19/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several DIU registers were being initialized either unnecessarily or to wrong values. 1) All interrupts were enabled even though there's no interrupt handler. Interrupts were left enabled when booting Linux. 2) Don't configure a dummy area descriptor, since we don't support ADs in U-Boot. 3) Don't configure any write-back buffer registers, since we don't use that mode. 4) The default values for the THRESHOLDS, SYN_POL, and PLUT registers should be used, so don't touch those registers either.

| * common/lcd: add protection from null bmp pointerNikita Kiryanov2012-09-21-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | If the bmp pointer is null then U-Boot will get stuck when trying to load the image. What's worse, it will get stuck before the U-Boot shell becomes available to the user, thus making it difficult to correct the situation. To protect from the above scenario, check if the pointer is valid. Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il>

* | disk: part_msdos: parse and store partition UUIDStephen Warren2012-09-25-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | The MSDOS/MBR partition table includes a 32-bit unique ID, often referred to as the NT disk signature. When combined with a partition number within the table, this can form a unique ID similar in concept to EFI/GPT's partition UUID. This patch generates UUIDs in the format 0002dd75-01, which matches the format expected by the Linux kernel. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* | disk: part_efi: parse and store partition UUIDStephen Warren2012-09-25-0/+33
| | | | | | | | | | | | | | | | | | | | | | Each EFI partition table entry contains a UUID. Extend U-Boot's struct disk_partition to be able to store this information, and modify get_partition_info_efi() to fill it in.

* | disk: get_device_and_partition() "auto" partition and cleanupStephen Warren2012-09-25-59/+171

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. If none, first valid paratition in device D. Note: In order to review this patch, it's probably easiest to simply look at the file contents post-application, rather than reading the patch itself. Signed-off-by: Rob Herring <rob.herring@calxeda.com> [swarren: Rob implemented scanning for bootable partitions.
