| | | | | | | | | | This causes widespread breakage due to the operation of the low-level code in crt0.S and cro0_64.S for ARM at least.

* x86: Switch to using generic global_data setupSimon Glass2015-08-14-1/+2
| | | | | | | | | | | There is quite a bit of assembler code that can be removed if we use the generic global_data setup. Less arch-specific code makes it easier to add new features and maintain the start-up code. Drop the unneeded code and adjust the hooks in board_f.c to cope.

* x86: fsp: Move FspInitEntry call to board_init_f()Bin Meng2015-07-14-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | The call to FspInitEntry is done in arch/x86/lib/fsp/fsp_car.S so far. It worked pretty well but looks not that good. Apart from doing too much work than just enabling CAR, it cannot read the configuration data from device tree at that time. Now we want to move it a little bit later as part of init_sequence_f[] being called by board_init_f(). This way it looks and works better in the U-Boot initialization path. Due to FSP's design, after calling FspInitEntry it will not return to its caller, instead it jumps to a continuation function which is given by bootloader with a new stack in system memory. The original stack in the CAR is gone, but its content is perserved by FSP and described by a bootloader temporary memory HOB. Technically we can recover anything we had before in the previous stack, but that is way too complicated. To make life much easier, in the FSP continuation routine we just simply call fsp_init_done() and jump back to car_init_ret() to redo the whole board_init_f() initialization, but this time with a non-zero HOB list pointer saved in U-Boot's global data so that we can bypass the FspInitEntry for the second time.

* 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>
