* video: Add SHARP LQ084S3LG01 LCD support on P1022DSTimur Tabi2011-08-04-1/+1
| | | | | | | | | | | | | | | | | The SHARP LQ084S3LG01 is a TFT LCD used on the P1022DS (revision "C") board. This device only supports 800x600 resolution, so if that resolution is selected, assume that this is the device. The device is attached to the LVDS port on the P1022DS board. The existing 800x600 entry (for the PDM360NG board) is actually 800x480, so we fix that. To support two different 800x resolutions, the Y-resolution is now passed to fsl_diu_init() and both values are used to pick the proper fb_videomode structure. The data for the 800x600 video mode is originally from Jiang Yutang. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Jiang Yutang <b14898@freescale.com>

* powerpc: use 'video-mode' environment variable to configure DIUTimur Tabi2011-04-28-42/+31
| | | | | | | | | | | | | | | | Use the 'video-mode' environment variable (for Freescale chips that have a DIU display controller) to designate the full video configuration. Previously, the DIU driver used the 'monitor' variable, and it was used only to determine the output video port. The old definition of the "monitor" environment variable only determines which video port to use for output. This variable was set to a number (0, 1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The resolution was hard-coded into board-specific code. The Linux command-line arguments needed to be hard-coded to the proper video definition string. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Anatolij Gustschin <agust@denx.de>
* powerpc/8xxx: Refactor fsl_ddr_get_spd into common code from boardKumar Gala2011-04-04-21/+0
| | | | | | | | | | | | | | Move fsl_ddr_get_spd into common mpc8xxx/ddr/main.c as most boards pretty much do the same thing. The only variations are in how many controllers or DIMMs per controller exist. To make this work we standardize on the names of the SPD_EEPROM_ADDRESS defines based on the use case of the board. We allow boards to override get_spd to either do board specific fixups to the SPD data or deal with any unique behavior of how the SPD eeproms are wired up.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

* 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) { ...

* fsl: improve the PIXIS code and fix a few bugsTimur Tabi2010-04-07-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx boards. This makes the code easier to read and more flexible. Delete pixis.h, because none of the exported functions were actually being used by any other file. Make all of the functions in pixis.c 'static'. Remove "#include pixis.h" from every file that has it. Remove some unnecessary #includes. Make 'pixis_base' into a macro, so that we don't need to define it in every function. Add "while(1);" loops at the end of functions that reset the board, so that execution doesn't continue while the reset is in progress. Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where appropriate. Replace ulong/uint with their spelled-out equivalents. Remove unnecessary typecasts, changing the types of some variables if necessary. Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make it easier for specific boards to support variations in the PIXIS registers sets. No current boards appears to need this feature. Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD. Apparently, "pixis_reset altbank" has never worked on this board.

* mpc86xx: set the DDR BATs after calculating true DDR sizeTimur Tabi2010-03-30-0/+2
| | | | | | | | | | | | | | | | | | | | After determining how much DDR is actually in the system, set DBAT0 and IBAT0 accordingly. This ensures that the CPU won't attempt to access (via speculation) addresses outside of actual memory. On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB and kept that way. If the system has less than 2GB of memory (typical for an MPC8610 HPCD), the CPU may attempt to access this memory during speculation. The zlib code is notorious for generating such memory reads, and indeed on the MPC8610, uncompressing the Linux kernel causes a machine check (without this patch). Currently we are limited to power of two sized DDR since we only use a single bat. If a non-power of two size is used that is less than CONFIG_MAX_MEM_MAPPED u-boot will crash.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
* 86xx: Reset updatePeter Tyser2009-02-16-0/+8
| | | | | | | | | | Update the 86xx reset sequence to try executing a board-specific reset function. If the board-specific reset is not implemented or does not succeed, then assert #HRESET_REQ. Using #HRESET_REQ is a more standard reset procedure than the previous method and allows all board peripherals to be reset if needed. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
