83  * dram_init_banksize() - Set up DRAM bank sizes
85  * This can be implemented by boards to set up the DRAM bank information in
86  * gd->bd->bi_dram(). It is called just before relocation, after dram_init()
95  * @return 0 if OK, -ve on error
113  * Run a list of commands separated by ; or even \0
115  * Note that if 'len' is not -1, then the command does not need to be nul
118  * @param cmd	List of commands to run, each separated bu semicolon
119  * @param len	Length of commands excluding terminator if known (-1 if not)
121  * @return 0 on success, or != 0 on error.
130  * ulong board_init_f_alloc_reserve - allocate reserved area
132  * This function is called by each architecture very early in the start-up
142  * board_init_f_init_reserve - initialize the reserved area(s)
152  * Board-specific Platform code can init serial earlier if needed
157  * arch_setup_gd() - Set up the global_data pointer
186  * setup_board_extra() - Fill in extra details in the bd_t structure
188  * @return 0 if OK, -ve on error
193  * arch_fsp_init() - perform firmware support package init
195  * Where U-Boot relies on binary blobs to handle part of the system init, this
202  * arch_cpu_init_dm() - init CPU after driver model is available
208  * @return 0 if OK, -ve on error
218  * On entry gd->start_addr_sp is pointing to the suggested top of the stack.
219  * The callee ensures gd->start_add_sp is 16-byte aligned, so architectures
222  * On exit gd->start_addr_sp and gd->irq_sp should be set to the respective
224  * gd->irq_sp is only required, if the architecture needs it.
226  * @return 0 if no error
231  * Show the DRAM size in a board-specific way
233  * This is used by boards to display DRAM information in their own way.
240  * arch_fixup_fdt() - Write arch-specific information to fdt
242  * Defined in arch/$(ARCH)/lib/bootm-fdt.c
245  * @return 0 if ok, or -ve FDT_ERR_... on failure
275  * env_get() - Look up the value of an environment variable
277  * In U-Boot proper this can be called before relocation (which is when the
287  * env_get_f() - Look up the value of an environment variable (early)
299  * env_get_ulong() - Return an environment variable as an integer value
301  * Most U-Boot environment variables store hex values. For those which store
302  * (e.g.) base-10 integers, this function can be used to read the value.
312  * env_get_hex() - Return an environment variable as a hex value
319  * @default_val:	Value to return on error
325  * Return -1 if variable does not exist (default to true)
330  * env_set() - set an environment variable
337  * @return 0 if OK, 1 on error
342  * env_update() - update sub value of an environment variable
349  * @return 0 if OK, 1 on error
355  * env_update_extract_subset() - extract subset value from an environment variable

369  * env_update() - update sub value of an environment variable
375  * @return 0 if OK, 1 on error
380  * env_exist() - check sub value of an environment variable is exist or not
389  * env_delete() - delete sub value of an environment variable
