227 | * board_init_f_mem() - Allocate global data and set stack position | |
228 | * | |
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 | |
232 | * below this. | |
233 | * | |
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. | |
241 | * | |
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. | |
