* Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk2010-10-29-3/+0
| | | | | | | | | | | By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-1/+1
| | | | | | | | | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

* MX51: Add IPU driver for video supportStefano Babic2010-10-22-0/+11
| | | | | | | | | | | | The patch is a porting of the IPU Linux driver developed by Freescale to have framebuffer functionalities in u-boot. The port is based on kernel 2.6.31 commit cc4fe714041805997b601fe8e5dd585d8a99297f, as delivered by Freescale [i.MX BSP]. Most features are dropped from the original driver and only LCD support is the goal of this porting. Signed-off-by: Stefano Babic <sbabic@denx.de>

* | davinci_emac: davinci_eth_set_mac_addr to ->write_hwaddrBen Gardiner2010-10-11-1/+0
|/ | | | | | | | | | | | | | | | | | | | | | This patch proposes to migrate the davinci_emac driver to using the eth_device->write_hwaddr function pointer as suggested by Ben Warren. All the davinci boards had the behaviour, prior to this patch, of sync'ing the environment variable enetaddr with the MAC address read from non-volatile storage on boot -- when the two locations disagreed, the environment variable value took precendence. This patch keeps the same behaviour but lets eth_initialize take care of it. This patch refactors davinci_emac setup in the boards so that the MAC address is read from non-volatile storage into the environment variable and then the environment variable value is use in eth_intialize. The only exception is the direct call to davinci_eth_set_mac_addr made by the da830evm board init which was changed into an assignment of the enetaddr field.

Multi-line variables have never been formally defined, allthough there is no reason not to use them. Now we define rules how to deal with them, allowing for import and export. - Function forceenv() and the related code in saveenv() was removed. At the moment this is causing build problems for the only user of this code (schmoogie - which has no entry in MAINTAINERS); may be fixed later by implementing the "env set -f" feature. Inconsistencies: - "printenv" will '\\'-escape the '\n' in multi-line variables, while "printenv var" will not do that. ====================================================================== Advantages: - "printenv" output much better readable (sorted) - faster! - extendable (additional variable properties can be added) - new, powerful features like "factory reset" or easy switching between several different environment settings ("profiles") Disadvantages: - Image size grows by typically 5...7 KiB (might shrink a bit again on systems with redundant environment with a following patch series) ====================================================================== Implemented: - env command with subcommands: - env print [arg ...] same as "printenv": print environment - env set [-f] name [arg ...] same as "setenv": set (and delete) environment variables ["-f" - force setting even for read-only variables - not implemented yet.] - end delete [-f] name not implemented yet ["-f" - force delete even for read-only variables] - env save same as "saveenv": save environment - env export [-t | -b | -c] addr [size] export internal representation (hash table) in formats usable for persistent storage or processing: -t: export as text format; if size is given, data will be padded with '\0' bytes; if not, one terminating '\0' will be added (which is included in the "filesize" setting so you can for exmple copy this to flash and keep the termination). -b: export as binary format (name=value pairs separated by '\0', list end marked by double "\0\0") -c: export as checksum protected environment format as used for example by "saveenv" command addr: memory address where environment gets stored size: size of output buffer With "-c" and size is NOT given, then the export command will format the data as currently used for the persistent storage, i. e. it will use CONFIG_ENV_SECT_SIZE as output block size and prepend a valid CRC32 checksum and, in case of resundant environment, a "current" redundancy flag. If size is given, this value will be used instead of CONFIG_ENV_SECT_SIZE; again, CRC32 checksum and redundancy flag will be inserted. With "-b" and "-t", always only the real data (including a terminating '\0' byte) will be written; here the optional size argument will be used to make sure not to overflow the user provided buffer; the command will abort if the size is not sufficient. Any remainign space will be '\0' padded. On successful return, the variable "filesize" will be set. Note that filesize includes the trailing/terminating '\0' byte(s). Usage szenario: create a text snapshot/backup of the current settings: => env export -t 100000 => era ${backup_addr} +${filesize} => cp.b 100000 ${backup_addr} ${filesize} Re-import this snapshot, deleting all other settings: => env import -d -t ${backup_addr} - env import [-d] [-t | -b | -c] addr [size] import external format (text or binary) into hash table, optionally deleting existing values: -d: delete existing environment before importing; otherwise overwrite / append to existion definitions -t: assume text format; either "size" must be given or the text data must be '\0' terminated -b: assume binary format ('\0' separated, "\0\0" terminated) -c: assume checksum protected environment format addr: memory address to read from size: length of input data; if missing, proper '\0' termination is mandatory - env default -f reset default environment: drop all environment settings and load default environment - env ask name [message] [size] same as "askenv": ask for environment variable - env edit name same as "editenv": edit environment variable - env run same as "run": run commands in an environment variable ====================================================================== TODO: - drop default env as implemented now; provide a text file based initialization instead (eventually using several text files to incrementally build it from common blocks) and a tool to convert it into a binary blob / object file. - It would be nice if we could add wildcard support for environment variables; this is needed for variable name auto-completion, but it would also be nice to be able to say "printenv ip*" or "printenv *addr*" - Some boards don't link any more due to the grown code size: DU405, canyonlands, sequoia, socrates. => cc: Matthias Fuchs <matthias.fuchs@esd-electronics.com>, Stefan Roese <sr@denx.de>, Heiko Schocher <hs@denx.de> - Dropping forceenv() causes build problems on schmoogie => cc: Sergey Kubushyn <ksi@koi8.net> - Build tested on PPC and ARM only; runtime tested with NOR and NAND flash only => needs testing!!

| * Make getenv() work before relocation.Wolfgang Denk2010-09-19-8/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, getenv() would work before relocation is most cases, even though it was not intended to be used that way. When switching to a hash table based implementation, this would break a number of boards. For convenience, we make getenv() check if it's running before relocation and, if so, use getenv_f() internally. Note that this is limited to simple cases, as we use a small static buffer (32 bytes) in the global data for this purpose. For this reason, it is also not a good idea to convert all current uses of getenv_f() into getenv() - some of the existing use cases need to be able to deal with longer variable values, so getenv_f() is still needed and recommended for use before relocation.
