* New command bootmenu: ANSI terminal boot menu supportPali Rohár2013-03-29-0/+1
| | | | | | | | | | | | | | | | | | The "bootmenu" command uses U-Boot menu interfaces and provides a simple mechanism for creating menus with several boot items. When running this command the menu will be assembled as defined by a set of environment variables which contain a title and command key-value pairs. The "Up" and "Down" keys are used for navigation through the items. Current active menu item is highlighted and can be selected using the "Enter" key. The command interprets and generates various ANSI escape sequencies, so for proper menu rendering and item selection the used terminal should support them.

It could be extended to others such as MD5 and the CRC algorithms. The syntax is modeled on those: hash <algorithm> <address> <length> [*<dest_addr> | <dest_envvar>] to calculate a hash, and: hash -v <algorithm> <address> <length> [*<verify_addr> | <verify_envvar>] to verify a hash.

* | fs: Add a Coreboot Filesystem (CBFS) driver and commandsGabe Black2012-10-22-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds CBFS support and some commands to use it to u-boot. These commands are: cbfsinit - Initialize CBFS support and pull all metadata into RAM. The end of the ROM is an optional parameter which defaults to the standard 0xffffffff and can be used to support multiple CBFSes in a system. The last one set up with cbfsinit is the one that will be used. cbfsinfo - Print information from the CBFS header. cbfsls - Print out the size, type, and name of all the files in the current CBFS. Recognized types are translated into symbolic names. cbfsload - Load a file from CBFS into memory. Like the similar command for fat filesystems, you can optionally provide a maximum size. Support for CBFS is compiled in when the CONFIG_CMD_CBFS option is specified. The CBFS driver can also be used programmatically from within u-boot. If u-boot needs something out of CBFS very early before the heap is configured, it won't be able to use the normal CBFS support which caches some information in memory it allocates from the heap. The cbfs_file_find_uncached function searches a CBFS instance without touching the heap.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for networking in SPL. Some devices are capable of loading SPL via network so it makes sense to load the main U-Boot binary via network too. This patch tries to use existing network code as much as possible. Unfortunately, it depends on environment which in turn depends on other code so SPL size is increased significantly. No effort was done to decouple network code and environment so far.

NOTE: Because the slave can not erase, write master's NOR flash by SRIO interface, so it can not modify the ENV parameters stored in master's NOR flash using "saveenv" or other commands. Master needs to: 1. Put the slave's ENV into it's own memory space. 2. Set an inbound SRIO window covered slave's ENV stored in master's memory space. Slave needs to: 1. Set a specific TLB entry in order to fetch ucode and ENV from master. 2. Set a LAW entry with the TargetID SRIO1 or SRIO2 for ucode and ENV.
