227 * board_init_f_mem() - Allocate global data and set stack position
229 * This function is called by each architecture very early in the start-up
230 * code to set up the environment for board_init_f(). It allocates space for
231 * global_data (see include/asm-generic/global_data.h) and places the stack
234 * This function requires a stack[1] Normally this is at @top. The function
235 * starts allocating space from 64 bytes below @top. First it creates space
236 * for global_data. Then it calls arch_setup_gd() which sets gd to point to
237 * the global_data space and can reserve additional bytes of space if
238 * required). Finally it allocates early malloc() memory
239 * (CONFIG_SYS_MALLOC_F_LEN). The new top of the stack is just below this,
240 * and it returned by this function.
242 * [1] Strictly speaking it would be possible to implement this function
243 * in C on many archs such that it does not require a stack. However this
244 * does not seem hugely important as only 64 byte are wasted. The 64 bytes
245 * are used to handle the calling standard which generally requires pushing
246 * addresses or registers onto the stack. We should be able to get away with
247 * less if this becomes important.

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