85 * 0x4030B800 to 0x4030CE00 as a public stack area. The ROM also

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

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

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