* common/cmd_bootm.c: fix subcommand processing in OS specific do_bootm_xxx() ↵Miao Yan2013-11-08-24/+8
| | | | | | | | | | | | | | | | | | | | | | | | | functions In commit "5c427e4: use BOOTM_STATE_OS_CMDLINE flag for plain bootm" and "3d187b3: Only pass BOOTM_STATE_OS_CMDLINE on PowerPC/MIPS", BOOTM_STATE_OS_CMDLINE was added to do_bootm for PowerPC and MIPS. This breaks other OSes (vxworks, netbsd, plan9,...) that don't support subcommand processing, e.g. they all contain the following code in their do_bootm_xxx(): if (flag & BOOTM_STATE_OS_PREP) return 0; if ((flag != 0) && (flag != BOOTM_STATE_OS_GO)) return 1; which will result a "subcommand not supported" error. This patch changes the above logic to: /* if not go command, pretend everything to be OK */ if (flag != BOOTM_STATE_OS_GO) return 0; Signed-off-by: Miao Yan <miao.yan@windriver.com>
* cmd_nvedit.c: Add env exists commandAndrew Ruder2013-11-08-0/+23
| | | | | | | | | | | | | | | | | | | | env exists is a way to test (in hush) if an environment variable exists. A workaround existed using printenv but this new command doesn't require all the stdout/stderr redirection to prevent printing information to the screen. Example: $ set testexists 1 $ env exists testexists && echo "yes" yes $ env exists testexists || echo "no" $ set testexists $ env exists testexists && echo "yes" $ env exists testexists || echo "no" no $ Signed-off-by: Andrew Ruder <andrew.ruder@elecsyscorp.com>

* pxe: fix handling of absolute pathsRob Herring2013-11-04-1/+8
| | | | | | | | | | | pxelinux and syslinux differ in their handling of absolute paths in menu files. A pxelinux path is aways prepended with the bootfile path while syslinux allows for absolute paths. u-boot was always treating a leading / as an absolute path breaking some pxelinux setups. Fix this by adding a flag to distinguish pxelinux vs. syslinux behavior. Reported-by: Ian Campbell <Ian.Campbell@citrix.com> Signed-off-by: Rob Herring <rob.herring@calxeda.com>

* Prevent null pointer dereference originating in cmd_pxe.cSteven Falco2013-10-14-42/+42
| | | | | | | | | | | | | | | | | | | | Pass a valid cmdtp into do_tftpb(), do_ext2load(), and do_get_fat(), to avoid possible crashes due to null pointer dereferencing. Commit d7884e047d08447dfd1374e9fa2fdf7ab36e56f5 does not go far enough. There is still at least one call chain that can result in a crash. The do_tftpb(), do_ext2load(), and do_get_fat() functions expect a valid cmdtp. Passing in NULL is particularly bad in the do_tftpb() case, because eventually boot_get_kernel() will be called with a NULL cmdtp: do_tftpb() -> netboot_common() -> bootm_maybe_autostart() -> do_bootm() -> do_bootm_states() -> bootm_find_os() -> boot_get_kernel() Around line 991 in cmd_bootm.c, boot_get_kernel() will dereference the null pointer, and the board will crash.

* cmd_ubi: add write.part command, to write a volume in multiple partsPaul Burton2013-10-09-15/+48
| | | | | | | | | | | | | | | | | | | | | | | This allows you to write data to an UBI volume when the amount of memory available to write that data from is less than the total size of the data. For example, you may split a root filesystem UBIFS image into parts, provide the total size of the image to the first write.part command and then use multiple write.part commands to write the subsequent parts of the volume. This results in a sequence of commands akin to: ext4load mmc 0:1 0x80000000 rootfs.ubifs.0 ubi write.part 0x80000000 root 0x08000000 0x18000000 ext4load mmc 0:1 0x80000000 rootfs.ubifs.1 ubi write.part 0x80000000 root 0x08000000 ext4load mmc 0:1 0x80000000 rootfs.ubifs.2 ubi write.part 0x80000000 root 0x08000000 This would write 384MiB of data to the UBI volume 'root' whilst only requiring 128MiB of said data to be held in memory at a time.

* Fix number base handling of "load" commandWolfgang Denk2013-10-07-13/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As documented, almost all U-Boot commands expect numbers to be entered in hexadecimal input format. (Exception: for historical reasons, the "sleep" command takes its argument in decimal input format.) This rule was broken for the "load" command; for details please see especially commits 045fa1e "fs: add filesystem switch libary, implement ls and fsload commands" and 3f83c87 "fs: fix number base behaviour change in fatload/ext*load". In the result, the load command would always require an explicit "0x" prefix for regular (i. e. base 16 formatted) input. Change this to use the standard notation of base 16 input format. While strictly speaking this is a change of the user interface, we hope that it will not cause trouble. Stephen Warren comments (see [1]): I suppose you can change the behaviour if you want; anyone writing "0x..." for their values presumably won't be affected, and if people really do assume all values in U-Boot are in hex, presumably nobody currently relies upon using non-prefixed values with the generic load command, since it doesn't work like that right now.

However, this is only valid / useful on PowerPC and MIPS, and causes a problem on ARM where we specifically do not use it. Rather than make this state fake pass like we do for GO on some arches (which need updating to use the GO state), we should just not pass CMDLINE except when it may be used, like before.

* | bootm: use BOOTM_STATE_OS_CMDLINE flag for plain bootmPaul Burton2013-09-20-2/+3
|/ | | | | | | | | | | | | | | | | | | A plain bootm used to call the architecture specific boot function with no flags, but was modified by commit 35fc84fa "Refactor the bootm command to reduce code duplication" to call the architecture specific boot function multiple times with various flags in sequence. The BOOTM_STATE_OS_CMDLINE flag was not used, indeed it seems that at least ARM prepares the command line on BOOTM_STATE_OS_PREP. However on MIPS since commit 59e8cbdb "MIPS: bootm: refactor initialisation of kernel cmdline" the command line is not prepared in response to a BOOTM_STATE_OS_PREP flag, only on BOOTM_STATE_OS_CMDLINE or a call with no flags. The end result is that a combination of those 2 commits leads to MIPS boards booting kernels with no command line arguments. An extra invocation of the architecture specific boot function with BOOTM_STATE_OS_CMDLINE fixes this. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

Also adds some safety to potential out-of-order descriptors. Change-Id: I16f69dfdd6793aa0fe930b5148d4521f3e5c3090 Signed-off-by: Julius Werner <jwerner@chromium.org>
