* | 85xx: Add support for not releasing secondary cores via 'mp_holdoff'Aaron Sierra2010-10-20-3/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | Some OSes require that secondary cores not be initialized when they are booted (eg VxWorks). By default when U-Boot is compiled with the CONFIG_MP option all secondary cores are brought out of reset and held in spinloops. Setting the "mp_holdoff" environment variable to 'yes' or '1' will cause U-Boot to leave secondary cores in their default state.

* | Add memory test feature for mpc85xx POST.York Sun2010-10-20-0/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The memory test is performed after DDR initialization when U-boot stills runs in flash and cache. On recent mpc85xx platforms, the total memory can be more than 2GB. To cover whole memory, it needs be mapped 2GB at a time using a sliding TLB window. After the testing, DDR is remapped with up to 2GB memory from the lowest address as normal. If memory test fails, DDR DIMM SPD and DDR controller registers are dumped for further debugging.

* powerpc: Cleanup BOOTFLAG_* referencesPeter Tyser2010-10-18-3/+11
| | | | | | | | | | | | Now that warm booting is not supported, there isn't a need for the BOOTFLAG_COLD and BOOTFLAG_WARM defines, so remove them. Note that this change makes the board info bd_bootflags field useless. It will always be set to 0, but we leave it around so that we don't break the board info structure that some OSes are expecting to be passed from U-Boot.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pumping line-rate traffic though a p4080 rev.2, which is configured to encrypt packets prior to forwarding through an IPsec tunnel, gets this error: of_platform ffe302000.jq: DECO: desc idx 22: LIODN error. DECO was trying to share from itself or from another DECO but the two Non-SEQ LIODN values didn't match or the "shared from" DECO's Descriptor required that the SEQ LIODNs be the same and they aren't. Since high traffic rates cause DECOs to begin to start sharing shared descriptors amongst themselves, and DECOs inherit job queue LIODNs when accessing shared descriptors, and a recently discovered rev.2 h/w erratum requires all sharing job queues in a partition have same liodn assignment, reassign the first job queue's liodn assignment to the rest.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default the trace broadcast is enabled on 44x systems. To reduce power consumption when instruction tracing is not needed, disable trace broadcast. Check External Debug Mode (EDM) bit to detect if it should be disabled or not.

| * ppc4xx: Cleanup of PVR detection code in cpu.cStefan Roese2010-09-23-71/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans the PVR detection code in check_cpu() up a bit. Basically the strings are better seperated, resulting in an easier to understand and maintain code version. The #ifdef's couldn't be removed easily because of two reasons: - Some SoC revisions have the same PVR, so need a way to differentiate between those two SoC's. - In some case statements registers only available in this SoC variant are referenced. Instead I moved the CONFIG_440 #ifdef a bit, so that 405 platforms don't add this 440 detection code and vice versa. Resulting in this U-Boot image size change: 405EX (Kilauea): 408 bytes less 440EPx (Sequoia): 604 bytes less 460EX (Canyonlands): 564 bytes less Signed-off-by: Stefan Roese <sr@denx.de> Cc: Wolfgang Denk <wd@denx.de>

| | | | | | | | | | | | | | | | | | This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO feature from U-Boot. It has only been implemented for PPC4xx and was not used at all.

| * ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese2010-09-23-716/+242
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors. All PPC4xx board config headers are changed to use this common NS16550 driver now. Tested on these boards: acadia, canyonlands, katmai, kilauea, sequoia, zeus Signed-off-by: Stefan Roese <sr@denx.de>
| * ppc4xx: Big header cleanup part 2, mostly PPC405 relatedStefan Roese2010-09-23-845/+610
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. As a part from this cleanup, the GPIO definitions for PPC405EP are corrected. The high and low parts of the registers (for example CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in the wrong order. This patch now fixes this issue by switching these xxxH and xxxL values. This brings the GPIO 405EP port in sync with all other PPC4xx ports. Signed-off-by: Stefan Roese <sr@denx.de>

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 Denk2010-09-19-2/+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.

| * Cleanup use of CONFIG_SYS_SRAM_BASE and CONFIG_SYS_SRAM_SIZEWolfgang Denk2010-09-19-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
