* fs: fat: extend for in-PBL supportAhmad Fatoum2020-07-111-1/+1
| | | | | | | | | | | The AT91 BootROM loads a boot.bin file from the first FAT partition into SRAM, when booting from MMC. To avoid the need for two barebox configurations for each of the bootloader stages, add PBL support for reading from FAT. This way each stage need only have a different PBL entry point.

* fs: jffs2: add initial support for reading jffs2Steffen Trumtrar2020-02-101-0/+1
| | | | | | | | | | | | | | | | | | | | | Import the jffs2 filesystem code from Linux v5.5-rc1 and convert it to work with barebox. Writing is *not* supported. Testing was done with a n25q256a-compatible QuadSPI chip on a SoCFPGA-based Socrates board.

* fs: dentry cache implementationSascha Hauer2018-07-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | This adds the Linux dentry cache implementation to barebox. Until now every filesystem driver resolves the full path to a file for itself. This leads to code duplication and is error prone since resolving paths is a complicated task. Also it can narrow down the lookup performance since barebox only knows ASCII paths and has no way of caching lookups. With this patch we get the Linux dcache implementation. The path resolving code from fs/namei.c is nearly taken as-is, minus the RCU and locking code. Dcaching is made simple as of now: We simply cache everything and never release any dentries. Although we do reference counting for inodes and dentries it is effectively not used yet. We never free anything until a fs is unmounted in which case we free everything no matter if references are taken or not. This patch also contains a wrapper in fs/legacy.c to support filesystems with the old API. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * barebox remote controlSascha Hauer2016-01-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the ability to control barebox over serial lines. The regular console is designed for human input and is unsuitable for controlling barebox from scripts since characters can be lost on both ends, the data stream contains escape sequences and the prompt cannot be easily matched upon. This approach is based on the RATP protocol. RATP packages start with a binary 0x01 which does not occur in normal console data. Whenever a 0x01 character is detected in the console barebox goes into RATP mode. The RATP packets contain a simple structure with a command/respone type and data for that type. Currently defined types are: BB_RATP_TYPE_COMMAND (host->barebox): Execute a command in the shell BB_RATP_TYPE_COMMAND_RETURN (barebox->host) Sends return value of the command back to the host, also means barebox is ready for the next command BB_RATP_TYPE_CONSOLEMSG (barebox->host) Console message from barebox Planned but not yet implemented are: BB_RATP_TYPE_PING (host->barebox) BB_RATP_TYPE_PONG (barebox->host) For testing purposes BB_RATP_TYPE_GETENV (host->barebox) BB_RATP_TYPE_GETENV_RETURN (barebox->host) Get values of environment variables Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Tested-by: Andrey Smirnov <andrew.smirnov@gmail.com>
* | fs: Add pstore filesystemMarkus Pargmann2015-12-101-0/+1
|/ | | | | | | | | | | | | | | | pstore is a persistent storage filesystem used for RAMOOPS. It is used to store console logs, panics, ftrace and other information in case of a crash/panic/oops/reboot. pstore is implemented for barebox as a read-only filesystem at the moment. It may be extended later on. The idea is to provide a way to extract essential data from the last running kernel. Most of the code is copied from the kernel. However this is only a lightweight implementation without real write support yet. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This format in the v1.0 allow you to store 6 types a binary stream for a unique hardware id: - bootloader - bootloader_version - description.gz - kernel - rootfs - firmware_version and you can easly add more binary stream type.

* Add suport for tftp as a filesystemSascha Hauer2012-02-191-0/+1
| | | | | | | | | | | | | | | | | | This adds tftp filesystem support. It currently duplicates significant amounts of the tftp (command) support. This is ok since we can eventually drop the original tftp command later. tftp is not really suitable to be handled as a filesystem. It lacks support for stat, reading directories and other things. Handling it as a filesystem has one big advantage though: tftp is no special case for boot scripts and/or commands anymore which makes them simpler. This implementation has some improvements to the original tftp command. It supports blocksize negotiation which speeds up transfers if the tftp server supports it. Also we can determine the filesize to transfer if the remote end supports it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
