cfi_flash_bank_addr(int bank_nr) returns the base addresses of the requested bank. Introducing this weak default enables boards to override this functions with a board specific version when required. This feature will be used in the lwmon5 board update, supporting runtime detection of 2 board revisions with different flash layouts. Signed-off-by: NStefan Roese <sr@denx.de>

This patch removes an unecessary check in the return statement. This is not needed, since "info" is initializes to NULL. And "info" will not be written to again, if the flash address is not found. Additionally "info" is not initialized to "0" but to "NULL". Signed-off-by: NStefan Roese <sr@denx.de>

Split the existing dram_init for da8xx when ARM reloc is enabled, like the changes to arch/arm/cpu/arm926ejs/orion5x/dram.c in 0f234d263b17ccf1b8fd776eb8c15b7cdb27a887 by Heiko Schocher <hs@denx.de>. Without these changes gd->ram_size is '0' which leads to incorrect relocation when CONFIG_SYS_ARM_WITHOUT_RELOC is defined and the board does not boot. We use get_ram_size to dynamically calculate the available RAM because it runs on different board version with different ram, as suggested by Heiko in private communication. Tested on a da850evm with 128M of DDR2 installed; with both CONFIG_SYS_ARM_WITHOUT_RELOC defined and undefined.

With -fPIC enabled, this variable needs an entry in the GOT, which causes the image size to exceed 2 KiB which is the maximum allowed for some systems.

This has been tested on at91sam9263 and STN8815. Again, I didn't check if it has bad effects on non-arm926 cores. Initially I had a "done" bit to only set up page tables at the beginning. However, since the aligmnent requirement was for the whole object file, this extra integer tool 16kB in BSS, so I chose to remove it. Also, note not all boards use PHYS_SDRAM, but it looks like it's the most used name (more than CONFIG_SYS_DRAM_BASE for example).

Merge the other significant source of board name duplication with the new boards.cfg file. I cleaned up most targets, but the ARM and MIPS trees are such a mess than I didn't bother. If those maintainers care, they can take are of it. While we're at it, we can be a bit more clever in the LIST_xxx handling and avoid duplicating the list names too.

The helpful shortcut for doing a board config + make was dropped recently as it conflicted with some new build code. However, the reason for using pattern targets originally was to avoid managing a duplicate list of boards. Since we now have one centralized place for a list of boards (the new boards.cfg), we don't need a pattern target -- we can generate the exact list of boards on the fly. So do just that. When cleaning things up, the top level gitignore file ignores all things that end with ".depend", but the clean target only deletes files that are named exactly ".depend". Keep these in sync by having the clean target punt all files that match the pattern that gitignore is using. Signed-off-by: NMike Frysinger <vapier@gentoo.org> Acked-by: NDetlev Zundel <dzu@denx.de>

Motivation: * Old environment code used a pessimizing implementation: - variable lookup used linear search => slow - changed/added variables were added at the end, i. e. most frequently used variables had the slowest access times => slow - each setenv() would calculate the CRC32 checksum over the whole environment block => slow * "redundant" envrionment was locked down to two copies * No easy way to implement features like "reset to factory defaults", or to select one out of several pre-defined (previously saved) sets of environment settings ("profiles") * No easy way to import or export environment settings ====================================================================== API Changes: - Variable names starting with '#' are no longer allowed I didn't find any such variable names being used; it is highly recommended to follow standard conventions and start variable names with an alphanumeric character - "printenv" will now print a backslash at the end of all but the last lines of a multi-line variable value. 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!!

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.
