* fdt: Add support for embedded device tree (CONFIG_OF_EMBED)Simon Glass2011-10-26-0/+1
| | | | | | | | | | | | | | | | | This new option allows U-Boot to embed a binary device tree into its image to allow run-time control of peripherals. This device tree is for U-Boot's own use and is not necessarily the same one as is passed to the kernel. The device tree compiler output should be placed in the $(obj) rooted tree. Since $(OBJCOPY) insists on adding the path to the generated symbol names, to ensure consistency it should be invoked from the directory where the .dtb file is located and given the input file name without the path. This commit contains my entry for the ugliest Makefile / shell interaction competition. Signed-off-by: Simon Glass <sjg@chromium.org>

* cache: include asm/cache.h for ARCH_DMA_MINALIGN definitionAnton Staaf2011-10-23-0/+8
| | | | | | | | | | | | | | | | | ARCH_DMA_MINALIGN will be used to allocate DMA buffers that are aligned correctly. In all current cases this means that the DMA buffer will be aligned to at least the L1 data cache line size of the configured architecture. If the board configuration file does not specify the architecture L1 data cache line size then the maximum line size of the architecture is used to align DMA buffers.

* Add pxe commandJason Hobbs2011-10-17-0/+6

* powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driverYork Sun2011-09-29-1/+3
| | | | | | | | | | | | | | | | | Unified DDR driver is maintained for better performance, robustness and bug fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of overall improvement. It requires changes for board files to customize platform-dependent parameters. To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx in the header file. No more boards will be accepted without such definition. Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1 and MPC8360 Rev 1.1/1.2 parts is not migrated to unified driver.

| | | | | | | | | | Some SOCs have discontiguously-numbered cores, and so we can't determine the valid core numbers via the FRR register any more.

* Add assert() for debug assertionsSimon Glass2011-09-10-0/+21
| | | | | | | | | | | | | | | assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined. This is useful when a condition is an error but a board reset is unlikely to fix it, so it is better to soldier on in hope. Assertion failures should be caught during development/test. It turns out that assert() is defined separately in a few places in U-Boot with various meanings. This patch cleans up some of these. Build errors exposed by this change (and defining DEBUG) are also fixed in this patch. Signed-off-by: Simon Glass <sjg@chromium.org>
* common: fix behavior of ROUND macro when input is already roundedAnton Staaf2011-09-07-1/+1
| | | | | | | | | | | | | | | | | | | Currently when you call ROUND with a value that is already a multiple of the second parameter it will return a value that is one multiple larger, instead of returning the value passed in. There are only two types of usage of ROUND currently, one in various config files to round CONFIG_SYS_MALLOC_LEN to a multiple of 4096 bytes. The other in cmd_sf.c where the incorrect behavior of ROUND is worked around be subtracting one from the length argument before passing it to ROUND. This patch fixes ROUND and removes the workaround from cmd_sf. It also results in all of the malloc pools that use ROUND to compute their size shrinking by 4KB.

For instance in Cortex-A8 these opertions will affect both L1 and L2 caches. In Cortex-A9 these will affect only L1 cache - D-cache operations supported: - Invalidate entire D-cache - Invalidate D-cache range - Flush(clean & invalidate) entire D-cache - Flush D-cache range - I-cache operations supported: - Invalidate entire I-cache - Add maintenance functions for TLB, branch predictor array etc. - Enable -march=armv7-a so that armv7 assembly instructions can be used Signed-off-by: Aneesh V <aneesh@ti.com>

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-0/+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.

* Rename getenv_r() into getenv_f()Wolfgang Denk2010-08-04-1/+1
| | | | | | | | | | | | | | | | | | | While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...
