| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows for creating a lzo compressed binary unsing the pbl. Only copy the piggydata if needed. Add CONFIG_PBL_FORCE_PIGGYDATA_COPY option In some case we need to copy the PIGGYDATA as the link address as example we run from SRAM and shutdown the SDRAM/DDR for reconfiguration but most of the time we just need to copy the executable code. based on Sascha Hauer Add compressed image support Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
| * | Add pre-bootloader (pbl) image supportJean-Christophe PLAGNIOL-VILLARD2012-08-031-0/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows for creating a pre-bootloader binary for - nand boot - mmc boot - compressed image The pbl will be incharge of the lowlevel init if needed. The barebox will skip it. Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and implement a dummy panic. For now on introduce dummy zbarebox* targets and c code that will contain later the decompressor. This only implemeted on ARM.

| * | mtd nand: implement buswidth detectionSascha Hauer2012-08-031-0/+3
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces a new NAND_BUSWIDTH_AUTO flag which can be used to automatically detect the nand buswidth. The id is always read in 8bit mode. An additional callback is needed to switch the nand controller into 16bit mode. This currently depends on a safe read_byte (always) and read_buf (for onfi-only flashes) callback. It has been tested on OMAP, but is not something that generally works. For this reason the existence of the set_buswidth callback is used to determine whether we are able to do autodetection or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a struct envfs_inode_end with more data. Today this will just containt the file mode to be able to add the symlink support. But this is compatible with the previous envfs version as they will do not care about the extra as the previous version is just reading the filename and then consume the extra data without using them.

| * Enable a way to provide the reason for "being here"Juergen Beisert2012-07-181-0/+27
| | | | | | | | | | | | | | | | | | | | Many architectures support a way to detect why the bootloader is running. This patch adds a global variable to be able to use the cause in some kind of shell code to do special things on demand. For example to do an emergency boot, when the last boot fails and the watchdog reactivate the hanging system.

This results in a huge autoconf.h file, on the order of 16k lines for a x86_64 defconfig. Fixing IS_ENABLED to be able to work on the smaller subset of just things that we really have defined is step one to fixing this. Which means it has to not choke when fed non-enabled options, such as: include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef] The original prototype of how to implement a C and preprocessor compatible way of doing this came from the Google+ user "comex ." in response to Linus' crowdsourcing challenge for a possible improvement on his earlier C specific solution: #define config_enabled(x) (__stringify(x)[0] == '1') In this implementation, I've chosen variable names that hopefully make how it works more understandable.

* fs: fix standard zero, full devicesSascha Hauer2012-07-042-0/+2
| | | | | | | | | | | | | | | | The standard devices are currently broken since they have the size ~0. As now files use loff_t as file size which is a signed type the read implementation gets confused and now returns -1. The current implementation also has the (somewhat theorical) problem that we do not have real streaming devices, so /dev/zero went out of zeroes after reading 4GB (or now LLONG_MAX). This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new file size flag FILE_SIZE_STREAM which makes it possible to create real stream devices instead.
