84 * 0x4030B800 to 0x4030CE00 as a public stack area. The ROM also

125 * The following are general good-enough settings for U-Boot. We set a

127 * function over binary size in the main portion of U-Boot as this is
128 * generally easily constrained later if needed. We enable the config
129 * options that give us information in the environment about what board
130 * we are on so we do not need to rely on the command prompt. We set a
131 * console baudrate of 115200 and use the default baud rate table.

179 * Our platforms make use of SPL to initalize the hardware (primarily
180 * memory) enough for full U-Boot to be loaded. We also support Falcon
181 * Mode so that the Linux kernel can be booted directly from SPL
182 * instead, if desired. We make use of the general SPL framework found
183 * under common/spl/. Given our generally common memory map, we set a
184 * number of related defaults and sizes here.
186 #define CONFIG_SPL_FRAMEWORK
188 * Place the image at the start of the ROM defined image space.
189 * We limit our size to the ROM-defined downloaded image area, and use the
190 * rest of the space for stack. We load U-Boot itself into memory at
191 * 0x80800000 for legacy reasons (to not conflict with older SPLs). We
192 * have our BSS be placed 1MiB after this, to allow for the default
193 * Linux kernel address of 0x80008000 to work, in the Falcon Mode case.
194 * We have the SPL malloc pool at the end of the BSS area.
