* Fix bootm to work on powerpc again (compressed uImage)Stefan Roese2013-06-28-5/+0
| | | | | | | | | | | | | | Patch 35fc84fa1 [Refactor the bootm command to reduce code duplication] breaks booting Linux (compressed uImage with fdt) on powerpc. boot_jump_linux() mustn't be called before boot_prep_linux() and boot_body_linux() have been called. So remove the superfluous call to boot_jump_linux() in arch/powerpc/lib/bootm.c as its called later on in this function.

* mkimage: Build signing only if board has CONFIG_FIT_SIGNATURESimon Glass2013-06-28-5/+6
| | | | | | | | | | | | | | | | At present mkimage is set up to always build with image signing support. This means that the SSL libraries (e.g. libssl-dev) are always required. Adjust things so that mkimage can be built with and without image signing, controlled by the presence of CONFIG_FIT_SIGNATURE in the board config file. If CONFIG_FIT_SIGNATURE is not enabled, then mkimage will report a warning that signing is not supported. If the option is enabled, but libraries are not available, then a build error similar to this will be shown: lib/rsa/rsa-sign.c:26:25: fatal error: openssl/rsa.h: No such file or directory Signed-off-by: Simon Glass <sjg@chromium.org>
* bootm: Disable interrupts before loading OSSimon Glass2013-06-28-26/+27
| | | | | | | | | | This restores the ordering of interrupt disable to what it what before commit 35fc84fa. It seems that on some archiectures (e.g. PowerPC) the OS is loaded into an interrupt region, which can cause problems if interrupts are still running.

* 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. Fixes 'spl export'.

* | Fix block device accesses beyond 2TiBSascha Silbe2013-06-26-24/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | image: Add support for signing of FIT configurationsSimon Glass2013-06-26-3/+798
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | mkimage: Add -r option to specify keys that must be verifiedSimon Glass2013-06-26-6/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, multiple public keys can be provided and U-Boot is not required to use all of them for verification. This is because some images may not be signed, or may be optionally signed. But we still need a mechanism to determine when a key must be used. This feature cannot be implemented in the FIT itself, since anyone could change it to mark a key as optional. The requirement for key verification must go in with the public keys, in a place that is protected from modification. Add a -r option which tells mkimage to mark all keys that it uses for signing as 'required'. If some keys are optional and some are required, run mkimage several times (perhaps with different key directories if some keys are very secret) using the -F flag to update an existing FIT.

| | | | | | | | | | | | | | | | | | | | | | | | | | When signing images it is sometimes necessary to sign with different keys at different times, or make the signer entirely separate from the FIT creation to avoid needing the private keys to be publicly available in the system. Add a -F option so that key signing can be a separate step, and possibly done multiple times as different keys are avaiable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FIT image verification requires public keys. Add a convenient option to mkimage to write the public keys to an FDT blob when it uses then for signing an image. This allows us to use: mkimage -f test.its -K dest.dtb -k keys test.fit and have the signatures written to test.fit and the corresponding public keys written to dest.dtb. Then dest.dtb can be used as the control FDT for U-Boot (CONFIG_OF_CONTROL), thus providing U-Boot with access to the public keys it needs.

* | image: Add RSA support for image signingSimon Glass2013-06-26-2/+1031
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | For tracing it is useful to run as much of U-Boot as possible so as to get a complete picture. Quite a bit of work happens in bootm, and we don't want to have to stop tracing before bootm starts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Additional duplication exists in bootz, so tidy that up as well. This is not intended to change behaviour, apart from minor fixes where the previously-duplicated code missed some chunks of code.

* | Clarify bootm OS argumentsSimon Glass2013-06-26-37/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This means that all functions can know that argv[0] is the first argument of which they need to take notice. Signed-off-by: Simon Glass <sjg@chromium.org>
