228 * board_init_f_mem() - Allocate global data and set stack position
230 * This function is called by each architecture very early in the start-up
231 * code to set up the environment for board_init_f(). It allocates space for
232 * global_data (see include/asm-generic/global_data.h) and places the stack
235 * This function requires a stack[1] Normally this is at @top. The function
236 * starts allocating space from 64 bytes below @top. First it creates space
237 * for global_data. Then it calls arch_setup_gd() which sets gd to point to
238 * the global_data space and can reserve additional bytes of space if
239 * required). Finally it allocates early malloc() memory
240 * (CONFIG_SYS_MALLOC_F_LEN). The new top of the stack is just below this,
241 * and it returned by this function.
243 * [1] Strictly speaking it would be possible to implement this function
244 * in C on many archs such that it does not require a stack. However this
245 * does not seem hugely important as only 64 byte are wasted. The 64 bytes
246 * are used to handle the calling standard which generally requires pushing
247 * addresses or registers onto the stack. We should be able to get away with
248 * less if this becomes important.

260 * Global Descriptor Table! So we we provide a function to carry out this task.
