* i2c, multibus: get rid of CONFIG_I2C_MUXHeiko Schocher2013-07-23-260/+6
| | | | | | | | | | | CONFIG_I2C_MUX is replaced through the new i2c multibus/multiadapter framework, configured through CONFIG_SYS_I2C. As CONFIG_I2C_MUX is only used on the keymile boards, and they are now completely moved to the new framework, remove CONFIG_I2C_MUX.

* bootm: Move fixup_silent_linux() earlier in the bootm stagesSimon Glass2013-07-17-4/+4
| | | | | | | | | | | | Before the bootm refactor, fixup_silent_linux() was done only in the monolithic bootm case, not in the subcommand case. With the refactor, it is done always, which is good. Unfortunately it is done too late, since it is the PREP or CMDLINE stages that set up the command line for Linux. Move fixup_silent_linux() into the LOADOS stage, which is where we find out the OS being used, and can thus decide whether to perform this step. Signed-off-by: Simon Glass <sjg@chromium.org>
* tpm: add AUTH1 cmds for LoadKey2 and GetPubKeyReinhard Pfau2013-07-16-0/+100
| | | | | | | | | | | | | | | | | | | | | | Extend the tpm library with support for single authorized (AUTH1) commands as specified in the TCG Main Specification 1.2. (The internally used helper functions are implemented in a way that they could also be used for double authorized commands if someone needs it.) Provide enums with the return codes from the TCG Main specification. For now only a single OIAP session is supported. OIAP authorized version of the commands TPM_LoadKey2 and TPM_GetPubKey are provided. Both features are available using the 'tpm' command, too. Authorized commands are enabled with CONFIG_TPM_AUTH_SESSIONS. (Note that this also requires CONFIG_SHA1 to be enabled.)

* Fix ext2/ext4 filesystem accesses beyond 2TiBFrederic Leroy2013-07-15-1/+2
| | | | | | | | | | | | | | | | | With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives We now use lbaint_t for partition offset to reflect the lbaint_t change, and access partitions beyond or crossing the 2.1TiB limit. This required changes to signature of ext4fs_devread(), and type of all variables relatives to block sector. ext2/ext4 fs uses logical block represented by a 32 bit value. Logical block is a multiple of device block sector. To avoid overflow problem when calling ext4fs_devread(), we need to cast the sector parameter. Signed-off-by: Frédéric Leroy <fredo@starox.org>

* bootm: Handle errors consistentlySimon Glass2013-07-12-13/+8
| | | | | | | | | | | | A recent bootm fix left the error path incomplete. If CONFIG_TRACE is set it may still not be a supported command, so cover that with the unsupported subcommand print. Once we handle BOOTM_STATE_OS_GO, we can just move into the error handler itself, no need for a goto there.

* bootm: Use selected configuration for ramdisk and fdtSimon Glass2013-07-12-6/+11
| | | | | | | | | | | | | | | If a specific configuraion is selected by the bootm command, e.g. with 'bootm 84000000#recoveryconf' we must honour this for not just the kernel, but also the ramdisk and FDT. In the conversion to using a common fit_image_load() function for loading images from FITs (commits a51ec63 and 53f375f) this feature was lost. Reinstate it by passing the selected configuration back from fit_image_load() to boot_get_kernel(), then use this configuration (which is stored in images->fit_uname_cfg) in both boot_get_ramdisk() and boot_get_fdt().

| | | | | | | | | | | With ELDK4.2 we were getting a warning that load_end may be used uninitialized in calling lmb_reserve. This could not be the case, however. If we re-order the checks (and make them slightly clearer as well) the warning goes away. bootm_load_os may only return 0 on success, BOOTM_ERR_OVERLAP in a non-fatal overlap (already covered in comments) or a fatal BOOTM_ERR that is covered in the error handler.

| | | | | | | | | | | | | In the recent bootm refactor, the PREP stage was missing in the bootz command. This causes unpredictable behaviour. The use of a local variable means that the reset of cmd_bootm.c does not in fact use the same image structure, so remove this. Also manually set the OS type to Linux, since this is the only possibility at present, and we need to select the right boot function. Signed-off-by: Simon Glass <sjg@chromium.org>

* bootm: Require boot function only if it is about to be usedSimon Glass2013-07-10-2/+5
| | | | | | | | | | | The original bootm code (before commit 35fc84f) did not check for a valid boot function in the subcommand case, which was incorrect. This check was introduced in all cases, but in fact we should only check for the function when we need it. Otherwise in some cases the check fires before the OS type is known.

* bootm: Disable interrupts only when loadingSimon Glass2013-07-10-24/+43

This is not correct - it should be done only once. Let's disable interrupts in the LOAD stage. Put the code in a function for clarity. Also, bootz lost its interrupt code altogether, so reinstate it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adjust_size_for_badblocks reduces the operation size to account for the block skipping done by the read/write functions when an interval (partition name or whole chip) is specified rather than a data amount. Erase does not do block skipping, except for erase.spread which takes a data amount rather than an interval (and thus already does not call adjust_size_for_badblocks). Calling adjust_size_for_badblocks when block skipping is not done means that if bad blocks are present, the "nand erase.part" and "nand erase.chip" commands will fail to erase blocks at the end of the interval.

| | | | | | | | | | | | | | | | | | | | This restores the ordering of interrupt disable to what it what before commit 35fc84fa.

* | cmd_bootm.c: Correct BOOTM_ERR_OVERLAP handlingTom Rini2013-06-28-27/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With 35fc84fa1 [Refactor the bootm command to reduce code duplication] we stopped checking the return value of bootm_load_os (unintentionally!) and simply returned if we had a non-zero return value from the function. This broke the valid case of a legacy image file of a single kernel loaded into an overlapping memory area (the default way of booting nearly all TI platforms). The best way to fix this problem in the new code is to make bootm_load_os be the one to see if we have a problem with this, and if it's fatal return BOOTM_ERR_RESET and if it's not BOOTM_ERR_OVERLAP, so that we can avoid calling lmb_reserve() but continue with booting. We however still need to handle the other BOOTM_ERR values so re-work do_bootm_states so that we have an error handler at the bottom we can goto for problems from bootm_load_os, or problems from the other callers (as the code was before). Add a comment to do_bootm_states noting the existing restriction on negative return values. Signed-off-by: Tom Rini <trini@ti.com> --- Changes in v2: - Rework so that only bootm_load_os and boot_selected_os head down into the err case code, and other errors simply return back to the caller.

* | Fix block device accesses beyond 2TiBSascha Silbe2013-06-26-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives. For some obscure reason, the current U-Boot code uses lbaint_t for the number of blocks to read (a rather optimistic estimation of how RAM sizes will evolve), but not for the starting address. Trying to access blocks beyond the 2TiB boundary will simply wrap around and read a block within the 0..2TiB range. We now use lbaint_t for block start addresses, too. This required changes to all block drivers as the signature of block_read(), block_write() and block_erase() in block_dev_desc_t changed. Signed-off-by: Sascha Silbe <t-uboot@infra-silbe.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While signing images is useful, it does not provide complete protection against several types of attack. For example, it it possible to create a FIT with the same signed images, but with the configuration changed such that a different one is selected (mix and match attack). It is also possible to substitute a signed image from an older FIT version into a newer FIT (roll-back attack). Add support for signing of FIT configurations using the libfdt's region support.

* | image: Add RSA support for image signingSimon Glass2013-06-26-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | RSA provides a public key encryption facility which is ideal for image signing and verification. Images are signed using a private key by mkimage. Then at run-time, the images are verified using a private key. This implementation uses openssl for the host part (mkimage). To avoid bringing large libraries into the U-Boot binary, the RSA public key is encoded using a simple numeric representation in the device tree. Signed-off-by: Simon Glass <sjg@chromium.org>

Quite a bit of work happens in bootm, and we don't want to have to stop tracing before bootm starts. Add a way of doing a 'fake' boot of the OS - which does everything up to the point where U-Boot is about to jump to the OS image. This allows tracing to record right until the end.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present the bootm code is mostly duplicated for the plain 'bootm' command and its sub-command variant. This makes the code harder to maintain and means that changes must be made to several places. Introduce do_bootm_states() which performs selected portions of the bootm work, so that both plain 'bootm' and 'bootm <sub_command>' can use the same code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | At present the arguments to bootm are processed in a somewhat confusing way. Sub-functions must know how many arguments their calling functions have processed, and the OS boot function must also have this information. Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in the same way. Adjust the code so that arguments are removed from the list before calling a sub-function.
