Or to be extra clear:
@@ -100,7 +100,7 @@
* the 1 actually activates the mapping of the first 32 KiB to 0x00000000.
*/
#define CONFIG_SYS_INIT_RAM_ADDR 0x10000
-#define CONFIG_SYS_INIT_RAM_SIZE 0x08000 /* FIXME: 40 KiB ? */
+#define CONFIG_SYS_INIT_RAM_SIZE 0xA000 /* 40 KiB */
#else
#define CONFIG_SYS_INIT_RAM_ADDR 0x0
#define CONFIG_SYS_INIT_RAM_SIZE 0x8000 /* 32 KiB */
is changing CONFIG_SYS_INIT_SP_ADDR which is in U-Boot proper. To
change the SPL stack pointer you use CONFIG_SPL_STACK which is what the
second hunk tweaks.
