Put it above BOOTMAPSZ to eliminate conflicts. 63 * 64 * kernel_addr_r must be within the first 128M of RAM in order for the 65 * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will 66 * decompress itself to 0x8000 after the start of RAM, kernel_addr_r 67 * should not overlap that area, or the kernel will have to copy itself 68 * somewhere else before decompression. Similarly, the address of any other 69 * data passed to the kernel shouldn't overlap the start of RAM. Pushing 70 * this up to 16M allows for a sizable kernel to be decompressed below the 71 * compressed load address. 72 * 73 * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for 74 * the compressed kernel to be up to 16M too. 75 * 76 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows 77 * for the FDT/DTB to be up to 1M, which is hopefully plenty. 78 */ 79 #define MEM_LAYOUT_ENV_SETTINGS \ 80 "scriptaddr=0x90000000\0" \ 81 "kernel_addr_r=0x81000000\0" \ 82 "fdt_addr_r=0x82000000\0" \ 83 "ramdisk_addr_r=0x82100000\0" 84 85 /* Defines for SPL */ 86 #define CONFIG_SPL_TEXT_BASE 0x80108000 87 #define CONFIG_SYS_SPL_MALLOC_START 0x80090000 88 #define CONFIG_SPL_STACK 0x800ffffc 89 90 #define CONFIG_SPL_LDSCRIPT "$(CPUDIR)/tegra30/u-boot-spl.lds" 91 92 /* Total I2C ports on Tegra30 */ 93 #define TEGRA_I2C_NUM_CONTROLLERS 5 94 95 #endif /* _TEGRA30_COMMON_H_ */ 96
