Put it above BOOTMAPSZ to eliminate conflicts. 64 * 65 * kernel_addr_r must be within the first 128M of RAM in order for the 66 * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will 67 * decompress itself to 0x8000 after the start of RAM, kernel_addr_r 68 * should not overlap that area, or the kernel will have to copy itself 69 * somewhere else before decompression. Similarly, the address of any other 70 * data passed to the kernel shouldn't overlap the start of RAM. Pushing 71 * this up to 16M allows for a sizable kernel to be decompressed below the 72 * compressed load address. 73 * 74 * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for 75 * the compressed kernel to be up to 16M too. 76 * 77 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows 78 * for the FDT/DTB to be up to 1M, which is hopefully plenty. 79 */ 80 #define MEM_LAYOUT_ENV_SETTINGS \ 81 "scriptaddr=0x10000000\0" \ 82 "kernel_addr_r=0x01000000\0" \ 83 "fdt_addr_r=0x02000000\0" \ 84 "ramdisk_addr_r=0x02100000\0" 85 86 /* Defines for SPL */ 87 #define CONFIG_SPL_TEXT_BASE 0x00108000 88 #define CONFIG_SYS_SPL_MALLOC_START 0x00090000 89 #define CONFIG_SPL_STACK 0x000ffffc 90 91 #define CONFIG_SPL_LDSCRIPT "$(CPUDIR)/tegra20/u-boot-spl.lds" 92 93 /* Align LCD to 1MB boundary */ 94 #define CONFIG_LCD_ALIGNMENT MMU_SECTION_SIZE 95 96 #ifdef CONFIG_TEGRA_LP0 97 #define TEGRA_LP0_ADDR 0x1C406000 98 #define TEGRA_LP0_SIZE 0x2000 99 #define TEGRA_LP0_VEC \ 100 "lp0_vec=" __stringify(TEGRA_LP0_SIZE) \ 101 "@" __stringify(TEGRA_LP0_ADDR) " " 102 #else 103 #define TEGRA_LP0_VEC 104 #endif 105 106 /* 107 * This parameter affects a TXFILLTUNING field that controls how much data is 108 * sent to the latency fifo before it is sent to the wire.
