* arc: clean-up init procedureAlexey Brodkin2015-04-03-4/+4
| | | | | | | | | | | | | | | | Intention behind this work was elimination of as much assembly-written code as it is possible. In case of ARC we already have relocation fix-up implemented in C so why don't we use C for U-Boot copying, .bss zeroing etc. It turned out x86 uses pretty similar approach so we re-used parts of code in "board_f.c" initially implemented for x86. Now assembly usage during init is limited to stack- and frame-pointer setup before and after relocation. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Simon Glass <sjg@chromium.org>

* common/board_f: move board_init_f_mem() from #else CONFIG_X86Alexey Brodkin2015-03-28-2/+4
| | | | | | | | | | | | | | | | | | | | Purpose of this change is to make it possible to re-use code currently used on X86 solely for other architectures. For example: * init_sequence_f_r * board_init_f_r Even though board_init_f_mem() has nothing to do with any particular architecture it won't work (at least in current implementation) for X86. This is because on X86 "gd" is an alias to function get_fs_gd_ptr(), thus we cannot assign anything to it. So this change separates selection of board_init_f_mem() from X86 while keeping it disabled for X86 still.

| * | common: board: support systems with where RAM ends beyond 4GBStephen Warren2015-03-04-0/+12
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some systems have so much RAM that the end of RAM is beyond 4GB. An example would be a Tegra124 system (where RAM starts at 2GB physical) that has more than 2GB of RAM. In this case, we can gd->ram_size to represent the actual RAM size, so that the actual RAM size is passed to the OS. This is useful if the OS implements LPAE, and can actually use the "extra" RAM. However, U-Boot does not implement LPAE and so must deal with 32-bit physical addresses. To this end, we enhance board_get_usable_ram_top() to detect the "over-sized" case, and limit the relocation addres so that it fits into 32-bits of physical address space.

* Introduce board_init_f_mem() to handle early memory layoutSimon Glass2015-02-12-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present on some architectures we set up the following before calling board_init_f(): - global_data - stack - early malloc memory Adding the code to support early malloc and global data setup to every arch's assembler start-up is a pain. Also this code is not actually architecture-specific. We can use common code for all architectures and with a bit of care we can write this code in C. Add a new function to deal with this. It should be called after memory is available, with a pointer to the top of the area that should be used before relocation. The function will set things up and return the lowest memory address that it allocated/used. That can then be set as the top of the stack. Note that on some archs this function will use the stack, so the stack pointer should be set to same value as is pased to board_init_f_mem(). A margin of 128 bytes will be left for this stack, so that it is not overwritten. This means that 64 bytes is wasted by this early call. This is not strictly necessary on several more modern archs, so we could remove this at the cost of some arch-dependent code. With this function there is no-longer any need for the assembler code to zero global_data or set up the early malloc pointers. Signed-off-by: Simon Glass <sjg@chromium.org>

* Add a simple malloc() implementation for pre-relocationSimon Glass2014-07-23-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are to have driver model before relocation we need to support some way of calling memory allocation routines. The standard malloc() is pretty complicated: 1. It uses some BSS memory for its state, and BSS is not available before relocation 2. It supports algorithms for reducing memory fragmentation and improving performace of free(). Before relocation we could happily just not support free(). 3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since this has been loaded anyway this is not really a problem. The simplest way to support pre-relocation malloc() is to reserve an area of memory and allocate it in increasing blocks as needed. This implementation does this. To enable it, you need to define the size of the malloc() pool as described in the README. It will be located above the pre-relocation stack on supported architectures. Note that this implementation is only useful on machines which have some memory available before dram_init() is called - this includes those that do no DRAM init (like tegra) and those that do it in SPL (quite a few boards). Enabling driver model preior to relocation for the rest of the boards is left for a later exercise. Signed-off-by: Simon Glass <sjg@chromium.org>
