* bootm: Reinstate special case for standalone imagesSimon Glass2014-01-14-9/+12
| | | | | | | | | | | | | | | | | | | | | For standalone images, bootm had a special case where the OS boot function was NULL but did actually exist. It was just called manually. This was removed by commit 35fc84fa which checks for the non-existence of this function before the special case is examined. There is no obvious reason why standalone is handled with a special case. Adjust the code so that standalone has a normal OS boot function. We still need a special case for when the function returns, but at least we can avoid the main problem. This is intended to fix the reported: ERROR: booting os 'U-Boot' (17) is not supported but needs testing. Signed-off-by: Simon Glass <sjg@chromium.org>

* 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_bootm.c: Only pass BOOTM_STATE_OS_CMDLINE on PowerPC/MIPSTom Rini2013-09-23-1/+4
| | | | | | | | | | | | In 5c427e4 we pass BOOTM_STATE_OS_CMDLINE as part of the bootm states to run, on all arches. 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.

* Fix loading freeze when netconsole is activeFrederic Leroy2013-09-20-0/+1
| | | | | | | | | | | | | Netconsole calls eth_halt() before giving control to another operating system. But the state machine of netconsole don't take it into account. Thus, netconsole calls network functions of an halted network device, making the whole system freeze. Rather than modifying the state machine of netconsole, we just unregister the current network device before booting. It does work because nc_send_packet() verifies that the current network device is not null. Signed-off-by: Frédéric Leroy <fredo@starox.org>
* 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>

* 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>
* 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.

* bootm: Use selected configuration for ramdisk and fdtSimon Glass2013-07-12-1/+2
| | | | | | | | | | | | | | | 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().

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.

* bootm: Add the missing PREP stage to bootz and correct image handlingSimon Glass2013-07-10-2/+3
| | | | | | | | | | | | | 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.

* 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
| | | | | | | | | | | With the move of the interrupt code to earlier in the sequence, we exposed a problem where the interrupts are disabled at each bootm stage. 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.

| | | | | | | | | | 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.

* Add a 'fake' go command to the bootm commandSimon Glass2013-06-26-2/+17
| | | | | | | | | | | | | | 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. 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.

* Refactor the bootm command to reduce code duplicationSimon Glass2013-06-26-241/+216
| | | | | | | | | | | | | | | | 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 Glass2013-06-26-18/+26
| | | | | | | | | | | | | | 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>

This doesn't work with sandbox, which has a U-Boot RAM buffer which is separate from the host machine's memory.

* fdt: Add option to default to most compatible conf in a fit imageGabe Black2012-11-12-0/+11
| | | | | | | | | | | | | | | | | | | | When booting a fit image with multiple configurations, the user either has to specify which configuration to use explicitly, or there has to be a default defined which is chosen automatically. 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.
