Even though board_init_f_mem() is not used on x86 today there's no reason to not use it in the future.
Moreover board_init_f_mem() has nothing to do with any particular architecture so move it away from #else /* CONFIG_X86 */

Any comments on this one? This is a prerequisite for ARC updates so would be good to have it merged sometime soon.
I must have missed something as it did not seem to change anything for ARC.
I meant this series - http://lists.denx.de/pipermail/u-boot/2015-March/208179.html
In particular here I wanted to use board_init_f_mem(): http://lists.denx.de/pipermail/u-boot/2015-March/208183.html
Note that in the previous patch http://lists.denx.de/pipermail/u-boot/2015-March/208182.html I re-used former X86-only code sections in common/board_f.c - that's why I did need board_init_f_mem() to be separated from #ifdef CONFIG_X86 #else - I wanted to use both branches :)
This breaks building on x86 though, so we can't take this patch as is. E.g.:
x86: + crownbay+common/board_f.c: In function ‘board_init_f_mem’: +common/board_f.c:1092:5: error: lvalue required as left operand of assignment
- gd = (struct global_data *)top;
^
That's why I wanted your opinion :) Sandbox didn't show any problems and I didn't do makeall.
Because in case of X86 "gd" is an alias to get_fs_gd_ptr() we cannot do such assignments.
So then we'll need to keep board_init_f_mem() disabled for X86 like that: --->8--- #ifndef CONFIG_X86 ulong board_init_f_mem(ulong top) { /* Leave space for the stack we are running with now */ top -= 0x40;
top -= sizeof(struct global_data); top = ALIGN(top, 16); gd = (struct global_data *)top; memset((void *)gd, '\0', sizeof(*gd));
#ifdef CONFIG_SYS_MALLOC_F_LEN top -= CONFIG_SYS_MALLOC_F_LEN; gd->malloc_base = top; #endif
return top; } #endif --->8---
Do you think that's OK? If so I'll send v2 shortly.
