| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently just validates variable types as decimal, hexidecimal, boolean, ip address, and mac address. Call env_acl_validate_setenv_params() from setenv() in fw_env.c. If the entry is not found in the env .flags, then look in the static one. This allows the env to override the static definitions, but prevents the need to have every definition in the environment distracting you. Need to build in _ctype for isdigit for Linux.

| * Add hash command to perform hashing using various algorithmsSimon Glass2012-12-11-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new command supports hashing SHA1 and SHA256. It could be extended to others such as MD5 and the CRC algorithms. The syntax is modeled on those: hash <algorithm> <address> <length> [*<dest_addr> | <dest_envvar>] to calculate a hash, and: hash -v <algorithm> <address> <length> [*<verify_addr> | <verify_envvar>] to verify a hash. Use CONFIG_CMD_HASH to enable the command, CONFIG_SHA1 to enable SHA1 and CONFIG_SHA256 to enable SHA256. The existing sha1sum command remains. Signed-off-by: Simon Glass <sjg@chromium.org>

| * env: Enable getenv_f() for SPL_BUILDStefan Roese2012-12-05-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | With this patch, getenv_f() can be included easily into the SPL binary. With this, SPL boards can now use getenv_f() to read environment variables (e.g. to detect if the OS or U-Boot shall be executed). In the approach this is done for env stored in NOR flash, as this will be used by an upcoming MPC5200 board port. Signed-off-by: Stefan Roese <sr@denx.de>
| * SPL: Port SPL framework to powerpcStefan Roese2012-12-05-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the SPL framework to be used on powerpc platforms and not only ARM. timer_init() does not exist on PPC systems. The timer (decrementer) is initialized and enabled in interrupt_init() here. And currently interrupt_init() is called after relocation to SDRAM. Since the only powerpc SPL implementation (a3m071) doesn't need a timer, let's remove this timer_init() call for PPC systems. Signed-off-by: Stefan Roese <sr@denx.de>
| * x86: Add CBMEM console driver for corebootVadim Bendebury2012-11-30-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch builds upon the recently introduced CBMEM console feature of coreboot. CBMEM console uses a memry area allocated by coreboot to store the console output. The memory area has a certain structure, which allows to determine where the buffer is, the buffer size and the location of the pointer in the buffer. This allows different phases of the firmware (rom based coreboot, ram based coreboot, u-boot after relocation with this change) to keep adding text to the same buffer. Note that this patch introduces a new console driver and adds the driver to the list of drivers to be used for console output, i.e. it engages only after u-boot relocates. Usiong CBMEM console for capturing the pre-relocation console output will be done under a separate change. >From Linux, run the cbmem.py utility (which is a part of the coreboot package) to see the output, e.g.: vvvvvvvvvvvvvvvvv SCSI: AHCI 0001.0300 32 slots 6 ports ? Gbps 0xf impl SATA mode flags: 64bit ilck stag led pmp pio ... Magic signature found Kernel command line: "cros_secure quiet loglevel=1 console=tty2... ^^^^^^^^^^^^^^^^^ Note that the entire u-boot output fits into the buffer only if the coreboot log level is reduced from the most verbose.

| * mmc: Fix incorrect handling of 'read' & 'write' commandsTaylor Hutt2012-11-27-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a malformed 'read' or 'write' command is issued, the Sandbox U-Boot can crash because the command-handling code does no error checking on the number of provided arguments. This change makes the mmc 'erase', 'read' and 'write' commands only function if the proper number of arguments are supplied. Also puts the else assignment at the beginning fo the if() statement to shortens the generated code. This removes an unnecessary jump from the generated code.

| * common: rework bouncebuf implementationStephen Warren2012-11-27-34/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current bouncebuf API requires all parameters to be passed to both bounce_buffer_start() and bounce_buffer_stop(). Modify the bouncebuf start function to accept a state structure as a parameter, and only require that state struct to be passed to the stop function. This simplifies usage of the bounce buffer by clients. Don't modify the data pointer, but rather store the temporary buffer in this state struct. The bouncebuf code ensures that client code can always use a single buffer pointer in the state structure, irrespective of whether a bounce buffer actually had to be allocated. Move cache management logic into the bounce buffer code, so that each client doesn't have to duplicate this. I believe there's no need to invalidate the buffer before a DMA operation, since flushing the cache should prevent any write-backs. Update the MXS MMC driver for this change.

This can be used by a packaging program to tell U-Boot about a kernel that has been downloaded alongside U-Boot. The value in the fdt is the offset of the kernel from the start of the U-Boot image, so we can find it just by adding CONFIG_SYS_TEXT_BASE. It is then fairly easy to put something like this in the environment variables in the board header file: "if test ${kernaddr} != \"\"; then "\ "echo \"Using bundled kernel\"; "\ "bootm ${kernaddr};" \ "fi; "\ /* rest of boot sequence follows here */ Signed-off-by: Simon Glass <sjg@chromium.org>

This change adds an option to change that behavior so that a configuration can be selected explicitly, or the configuration which has the device tree that claims to be compatible with the earliest item in U-Boot's device tree. In other words, if U-Boot claimed to be compatible with A, B, and then C, and the configurations claimed to be compatible with A, D and B, D and D, E, the first configuration, A, D, would be chosen. Both the first and second configurations match, but the first one matches a more specific entry in U-Boot's device tree. The order in the kernel's device tree is ignored.
