| | | | | | | | | | | | | | | | | | | | | | | | | | Commit b3dd64f5d537 "bootm: use genimg_get_kernel_addr()" introduced a bug for booting FIT image. It's because calling fit_parse_config() twice will give us wrong value in img_addr. Add a new function genimg_get_kernel_addr_fit() whichl will always return fit_uname_config and fit_uname_kernel for CONFIG_FIT. genimg_get_kernel_addr() will ignore those to parameters.

* | pxe: clear Bootfile before returningStephen Warren2014-08-09-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When "pxe boot" downloads the initrd/kernel/DTB, netboot_common() saves the downloaded filename to global variable BootFile. If the boot operation is aborted, this global state is not cleared. If "dhcp" is executed later without any arguments, BootFile is not cleared, and when the DHCP response is received, BootpCopyNetParams() writes the value into environment variable bootfile. This causes the following scenario: * Boot script executes dhcp; pxe get; pxe boot * User CTRL-C's the PXE menu, which causes the first menu item to be booted, which causes some file to be downloaded. (This boot-on-CTRL-C behaviour is arguably a bug too, but it's a separate bug and the bug this patch fixes would still exist if the user simply waited to press CTRL-C until "pxe boot" started downloading files) * User CTRL-C's the file downloads, but the filename is still written to the bootfile environment variable. * User re-runs the boot command, which in my case executes "dhcp; pxe get; pxe boot" again, and "dhcp" picks up the saved bootfile environment variable and proceeds to download a file that it shouldn't. To solve this, modify the implementation of "pxe get" to clear BootFile if the whole boot operation fails, which avoids this whole mess. An alternative would be to modify netboot_common() such that the no- arguments case explicitly clears the global variable BootFile. However, that would prevent the following command sequences from working: $ dhcp filename # downloads "filename" $ dhcp # downloads $bootfile, i.e. "filename" or: $ setenv bootfile filename $ dhcp # downloads $bootfile, i.e. "filename" ... and I assume someone relies on U-Boot working that way.

* | Add a flag indicating when the serial console is readySimon Glass2014-07-23-2/+2
| | | | | | | | | | | | | | | | | | | | For sandbox we have a fallback console which is used very early in U-Boot, before serial drivers are available. Rather than try to guess when to switch to the real console, add a flag so we can be sure. This makes sure that sandbox can always output a panic() message, for example, and avoids silent failure (which is very annoying in sandbox). Signed-off-by: Simon Glass <sjg@chromium.org>
* | console: Remove vprintf() optimisation for sandboxSimon Glass2014-07-23-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | If the console is not present, we try to reduce overhead by stopping any output in vprintf(), before it gets to putc(). This is of dubious merit in general, but in the case of sandbox it is incorrect since we have a fallback console which reports errors very early in U-Boot. If this is defeated U-Boot can hang or exit with no indication of what is wrong. Remove the optimisation for sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
* | stdio: Provide functions to add/remove devices using stdio_devSimon Glass2014-07-23-8/+24
| | | | | | | | | | | | | | | | | | The current functions for adding and removing devices require a device name.

* | dm: Allow drivers to be marked 'before relocation'Simon Glass2014-07-23-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver model currently only operates after relocation is complete. In this state U-Boot typically has a small amount of memory available. In adding support for driver model prior to relocation we must try to use as little memory as possible. In addition, on some machines the memory has not be inited and/or the CPU is not running at full speed or the data cache is off. These can reduce execution performance, so the less initialisation that is done before relocation the better. An immediately-obvious improvement is to only initialise drivers which are actually going to be used before relocation. On many boards the only such driver is a serial UART, so this provides a very large potential benefit. Allow drivers to mark themselves as 'pre-reloc' which means that they will be initialised prior to relocation. This can be done either with a driver flag or with a 'dm,pre-reloc' device tree property. To support this, the various dm scanning function now take a 'pre_reloc_only' parameter which indicates that only drivers marked pre-reloc should be bound.

* | stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-25/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away.

* | Add a simple malloc() implementation for pre-relocationSimon Glass2014-07-23-0/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are to have driver model before relocation we need to support some way of calling memory allocation routines. The standard malloc() is pretty complicated: 1. It uses some BSS memory for its state, and BSS is not available before relocation 2. It supports algorithms for reducing memory fragmentation and improving performace of free(). Before relocation we could happily just not support free(). 3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since this has been loaded anyway this is not really a problem. The simplest way to support pre-relocation malloc() is to reserve an area of memory and allocate it in increasing blocks as needed. This implementation does this. To enable it, you need to define the size of the malloc() pool as described in the README. It will be located above the pre-relocation stack on supported architectures. Note that this implementation is only useful on machines which have some memory available before dram_init() is called - this includes those that do no DRAM init (like tegra) and those that do it in SPL (quite a few boards). Enabling driver model preior to relocation for the rest of the boards is left for a later exercise. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | endings When this option is enabled, CRLF is treated like LF when importing environments from text files, which means CRs ('\r') in front of LFs ('\n') are just ignored.
