* Remove HMI10 board supportWolfgang Denk2010-09-19-717/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes caused that the HMI10 board now is included in the boards built by MAKEALL, which revealed that compilation for this board has been broken for a long time: ps2ser.c: In function 'ps2ser_init': ps2ser.c:155: error: 'UART_LCR' undeclared (first use in this function) ps2ser.c:155: error: (Each undeclared identifier is reported only once ps2ser.c:155: error: for each function it appears in.) ps2ser.c:156: error: 'UART_DLL' undeclared (first use in this function) ps2ser.c:157: error: 'UART_DLM' undeclared (first use in this function) ps2ser.c:159: error: 'UART_IER' undeclared (first use in this function) ps2ser.c:160: error: 'UART_MCR' undeclared (first use in this function) ps2ser.c:161: error: 'UART_FCR' undeclared (first use in this function) ps2ser.c:162: error: 'UART_FCR_ENABLE_FIFO' undeclared (first use in this function) ps2ser.c:166: error: 'UART_LSR' undeclared (first use in this function) ps2ser.c: In function 'ps2ser_putc': ps2ser.c:198: error: 'UART_LSR' undeclared (first use in this function) ps2ser.c:200: error: 'UART_TX' undeclared (first use in this function) ps2ser.c: In function 'ps2ser_getc_hw': ps2ser.c:224: error: 'UART_LSR' undeclared (first use in this function) ps2ser.c:225: error: 'UART_RX' undeclared (first use in this function) ps2ser.c: In function 'ps2ser_interrupt': ps2ser.c:293: error: 'UART_IIR' undeclared (first use in this function) The board is orphaned, and AFAICT has reached EOL.

* da8xx: fixup ARM relocation supportBen Gardiner2010-09-19-0/+18
| | | | | | | | | | | | | | | | | | | | | 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.

* Makefile: restore support for board shortcut targetsMike Frysinger2010-09-19-3/+4
| | | | | | | | | | | | | | | | | 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: Mike Frysinger <vapier@gentoo.org> Acked-by: Detlev Zundel <dzu@denx.de>
* New implementation for internal handling of environment variables.Wolfgang Denk2010-09-19-776/+1186

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 Denk2010-09-19-39/+51
| | | | | | | | | | | | | | | | | | | 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.

* Add hash table support as base for new environment codeWolfgang Denk2010-09-19-0/+828
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implementation is based on code from uClibc-0.9.30.3 but was modified and extended for use within U-Boot. Major modifications and extensions: * hsearch() [modified / extended]: - While the standard version does not make any assumptions about the type of the stored data objects at all, this implementation works with NUL terminated strings only. - Instead of storing just pointers to the original objects, we create local copies so the caller does not need to care about the data any more. - The standard implementation does not provide a way to update an existing entry. This version will create a new entry or update an existing one when both "action == ENTER" and "item.data != NULL". - hsearch_r(): Instead of returning 1 on success, we return the index into the internal hash table, which is also guaranteed to be positive. This allows us direct access to the found hash table slot for example for functions like hdelete(). * hdelete() [added]: - The standard implementation of hsearch(3) does not provide any way to delete any entries from the hash table. We extend the code to do that. * hexport() [added]: - Export the data stored in the hash table in linearized form: Entries are exported as "name=value" strings, separated by an arbitrary (non-NUL, of course) separator character. This allows to use this function both when formatting the U-Boot environment for external storage (using '\0' as separator), but also when using it for the "printenv" command to print all variables, simply by using as '\n" as separator. This can also be used for new features like exporting the environment data as text file, including the option for later re-import. - The entries in the result list will be sorted by ascending key values. * himport() [added]: - Import linearized data into hash table. This is the inverse function to hexport(): it takes a linear list of "name=value" pairs and creates hash table entries from it. - Entries without "value", i. e. consisting of only "name" or "name=", will cause this entry to be deleted from the hash table. - The "flag" argument can be used to control the behaviour: when the H_NOCLEAR bit is set, then an existing hash table will kept, i. e. new data will be added to an existing hash table; otherwise, old data will be discarded and a new hash table will be created. - The separator character for the "name=value" pairs can be selected, so we both support importing from externally stored environment data (separated by NUL characters) and from plain text files (entries separated by newline characters). - To allow for nicely formatted text input, leading white space (sequences of SPACE and TAB chars) is ignored, and entries starting (after removal of any leading white space) with a '#' character are considered comments and ignored. - NOTE: this means that a variable name cannot start with a '#' character. - When using a non-NUL separator character, backslash is used as escape character in the value part, allowing for example fo multi-line values. - In theory, arbitrary separator characters can be used, but only '\0' and '\n' have really been tested.

* Cleanup use of CONFIG_SYS_SRAM_BASE and CONFIG_SYS_SRAM_SIZEWolfgang Denk2010-09-19-8/+8
| | | | | | | | | | | | | | | | | | | | | | Traditionally many boards used local definitions for SRAM base address and size (like SRAM_BASE, SRAM_LEN and/or SRAM_SIZE), while the (now) "official" names are CONFIG_SYS_SRAM_BASE and CONFIG_SYS_SRAM_SIZE. The corresponding code in arch/powerpc/lib/board.c was board specific, and has never actually been maintained well. Replace this by feature- specific code and adapt the boards that actually use this. NOTE: there is still a ton of boards using the old #defines, which therefor contain incorrect values in bi_sramstart and bi_sramsize. All respective board maintainers are requested to clean up their respective configurations. Thanks.
