* Introduce generic pre-relocation board_f.cSimon Glass2013-03-15-6/+6
| | | | | | | | | | | | This file handles common pre-relocation init for boards which use the generic framework. It starts up the console, DRAM, performs relocation and then jumps to post-relocation init.

* Declare watchdog functions in watchdog.hSimon Glass2013-03-15-9/+4
| | | | | | | | These functions are only available for powerpc and are not declared in a header file. We want to use the rest function in two places (board_f and board_r), so declare the functions in watchdog.h. Signed-off-by: Simon Glass <sjg@chromium.org>
* Change stub example to use asm-generic/sections.hSimon Glass2013-03-15-9/+9

* Introduce generic link section.h symbol filesSimon Glass2013-03-15-4/+330
| | | | | | | | | | | | | | | | | | We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>
* Replace __bss_end__ with __bss_endSimon Glass2013-03-15-93/+93
| | | | | | | | | | | | | Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>

* mpc512x: add common LAW and Chip Select configurationAnatolij Gustschin2013-03-09-0/+96
| | | | | | | | | | | | | Currently each mpc512x board has its own LAW and CS config code, we should avoid this code duplication. Allow all boards to use common code by only defining LAW and CS config macros like CONFIG_SYS_CSx_START, CONFIG_SYS_CSx_SIZE and CONFIG_SYS_CSx_CFG. Also allow common configuration of additional CS parameters by CONFIG_SYS_CS_ALETIMING, CONFIG_SYS_CS_BURST, CONFIG_SYS_CS_DEADCYCLE and CONFIG_SYS_CS_HOLDCYCLE options.

* mpc5200: spl_boot.c: Change init oder to first enable printfStefan Roese2013-03-09-6/+14
| | | | | | | | | | On MPC5200, the initial RAM (and gd) is located in the internal SRAM. So we can actually call the preloader console init code before calling initdram(). This makes serial output (printf) available very early, even before SDRAM init, which has been an U-Boot priciple from day 1. Signed-off-by: Stefan Roese <sr@denx.de>
* x86: Add error checking to x86 relocation codeSimon Glass2013-03-04-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This does not actually change normal behaviour, but adds a check that should detect corruption of relocation data (e.g. by using BSS data prior to relocation). Also add additional debugging output when enabled. During this investigation, two situations have been seen: 1. calculate_relocation_address(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; turns into 111166f: b8 83 c4 17 01 mov $0x117c483,%eax whih is beyond the end of bss: 0117b484 g .bss 00000000 __bss_end Somehow the __bss_end here is 255 bytes ahead. 2. do_elf_reloc_fixups(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; Here the __text_start is 0 in the file: 1111d9f: bb a0 e0 13 01 mov $0x113e0a0,%ebx 1111da4: 81 ef 00 00 00 00 sub $0x0,%edi As it happens, both of these are in pre-relocation code. For these reasons we silent check and ignore bad relocations. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Support relocation of FDT on start-upSimon Glass2013-03-04-2/+46
| | | | | | | With CONFIG_OF_CONTROL we may have an FDT in the BSS region. Relocate it up with the rest of U-Boot to keep the rest of memory free. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Rearrange the output input to remove BSSSimon Glass2013-03-04-7/+12
| | | | | | | At present BSS data is including in the image, which wastes binary space. Remove it by rearranging the sections so that BSS is last. Signed-off-by: Simon Glass <sjg@chromium.org>

* x86: Permit bootstage and timer data to be used prior to relocationSimon Glass2013-03-04-18/+16
| | | | | | | | | It is useful to be able to access the timer before U-Boot has relocated so that we can fully support bootstage. Add new global_data members to support this. Signed-off-by: Simon Glass <sjg@chromium.org>

* x86: Add function to get top of usable ramSimon Glass2013-03-04-24/+22
| | | | | | | | | | | | | The memory layout calculations are done in calculate_relocation_address(), and coreboot has its own version of this function. But in fact all we really need is to set the top of usable RAM, and then the base version will work as is. So instead of allowing the whole calculate_relocation_address() function to be replaced, create board_get_usable_ram_top() which can be used by a board to specify the top of the area where U-Boot relocations to.

| * sandbox: Add un/map_sysmen() to deal with sandbox's ram_bufSimon Glass2013-02-28-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sandbox doesn't actually provide U-Boot access to the machine's physical memory. Instead it provides a RAM buffer of configurable size, and all memory accesses are within that buffer. Sandbox memory starts at 0 and is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer might produce unpredictable results in the event of an error, and would expose the host machine's memory architecture to the sandbox U-Boot. Most U-Boot functions assume that they can just access memory at given address. For sandbox this is not true. Add a map_sysmem() call which converts a U-Boot address to a system address. In most cases this is a NOP, but for sandbox it returns a pointer to that memory inside the RAM buffer. To get a U-Boot feature to work correctly within sandbox, you should call map_sysmem() to get a pointer to the address, and then use that address for any U-Boot memory accesses.

Multiplexing the console between the serial port and a keyboard uses a polling method of checking if characters are available; this means that the serial console must be non-blocking when attempting to read characters.
