exists, unlike the similar options in the Linux kernel. Do not
set these options unless they apply!

the console jump but can help speed up operation when scrolling
is slow.
+ CONFIG_LCD_ROTATION
+
+ Sometimes, for example if the display is mounted in portrait
+ mode or even if it's mounted landscape but rotated by 180degree,
+ we need to rotate our content of the display relative to the
+ framebuffer, so that user can read the messages which are
+ printed out.
+ Once CONFIG_LCD_ROTATION is defined, the lcd_console will be
+ initialized with a given rotation from "vl_rot" out of
+ "vidinfo_t" which is provided by the board specific code.
+ The value for vl_rot is coded as following (matching to
+ fbcon=rotate:<n> linux-kernel commandline):
+ 0 = no rotation respectively 0 degree
+ 1 = 90 degree rotation
+ 2 = 180 degree rotation
+ 3 = 270 degree rotation
+
+ If CONFIG_LCD_ROTATION is not defined, the console will be
+ initialized with 0degree rotation.

example, some LED's) on your board. At the moment,
the following checkpoints are implemented:
-- Detailed boot stage timing
- CONFIG_BOOTSTAGE
- Define this option to get detailed timing of each stage
- of the boot process.
-
- CONFIG_BOOTSTAGE_USER_COUNT
- This is the number of available user bootstage records.
- Each time you call bootstage_mark(BOOTSTAGE_ID_ALLOC, ...)
- a new ID will be allocated from this stash. If you exceed
- the limit, recording will stop.
-
- CONFIG_BOOTSTAGE_REPORT
- Define this to print a report before boot, similar to this:
-
- Timer summary in microseconds:
- Mark Elapsed Stage
- 0 0 reset
- 3,575,678 3,575,678 board_init_f start
- 3,575,695 17 arch_cpu_init A9
- 3,575,777 82 arch_cpu_init done
- 3,659,598 83,821 board_init_r start
- 3,910,375 250,777 main_loop
- 29,916,167 26,005,792 bootm_start
- 30,361,327 445,160 start_kernel
-
- CONFIG_CMD_BOOTSTAGE
- Add a 'bootstage' command which supports printing a report
- and un/stashing of bootstage data.
-
- CONFIG_BOOTSTAGE_FDT
- Stash the bootstage information in the FDT. A root 'bootstage'
- node is created with each bootstage id as a child. Each child
- has a 'name' property and either 'mark' containing the
- mark time in microsecond, or 'accum' containing the
- accumulated time for that bootstage id in microseconds.
- For example:
-
- bootstage {
- 154 {
- name = "board_init_f";
- mark = <3575678>;
- };
- 170 {
- name = "lcd";
- accum = <33482>;
- };
- };
-
- Code in the Linux kernel can find this in /proc/devicetree.

CONFIG_SPL_STACK
Adress of the start of the stack SPL will use
+ CONFIG_SPL_PANIC_ON_RAW_IMAGE
+ When defined, SPL will panic() if the image it has
+ loaded does not have a signature.
+ Defining this is useful when code which loads images
+ in SPL cannot guarantee that absolutely all read errors
+ will be caught.
+ An example is the LPC32XX MLC NAND driver, which will
+ consider that a completely unreadable NAND block is bad,
+ and thus should be skipped silently.
+
CONFIG_SPL_RELOC_STACK
Adress of the start of the stack SPL will use after
relocation. If unspecified, this is equal to
to this new framework over time. Defining this will disable the
arch/foo/lib/board.c file and use common/board_f.c and
common/board_r.c instead. To use this option your architecture
- must support it (i.e. must define __HAVE_ARCH_GENERIC_BOARD in
- its config.mk file). If you find problems enabling this option on
- your board please report the problem and send patches!
