Tested with U-Boot running on an emulated Versatile Express, with either A9 or A15 CoreTile. Signed-off-by: Francesco Lavra --- Changes in v2: Use drive_get_next() instead of drive_get() to get a backing storage for each flash bank. hw/vexpress.c | 24 ++++++++++++++++++++++-- 1 files changed, 22 insertions(+), 2 deletions(-) diff --git a/hw/vexpress.c b/hw/vexpress.c index 454c2bb..2ffeab1 100644 --- a/hw/vexpress.c +++ b/hw/vexpress.c @@ -29,8 +29,12 @@ #include "sysemu.h" #include "boards.h" #include "exec-memory.h" +#include "blockdev.h" +#include "flash.h" #define VEXPRESS_BOARD_ID 0x8e0 +#define VEXPRESS_FLASH_SIZE (64 * 1024 * 1024) +#define VEXPRESS_FLASH_SECT_SIZE (256 * 1024) static struct arm_boot_info vexpress_binfo; @@ -355,6 +359,7 @@ static void vexpress_common_init(const VEDBoardInfo *daughterboard, qemu_irq pic[64]; uint32_t proc_id; uint32_t sys_id; + DriveInfo *dinfo; ram_addr_t vram_size, sram_size; MemoryRegion *sysmem = get_system_memory(); MemoryRegion *vram = g_new(MemoryRegion, 1); @@ -410,8 +415,23 @@ static void vexpress_common_init(const VEDBoardInfo *daughterboard, sysbus_create_simple("pl111", map[VE_CLCD], pic[14]); - /* VE_NORFLASH0: not modelled */ - /* VE_NORFLASH1: not modelled */ + dinfo = drive_get_next(IF_PFLASH); + if (!pflash_cfi01_register(map[VE_NORFLASH0], NULL, "vexpress.flash0", + VEXPRESS_FLASH_SIZE, dinfo ? dinfo->bdrv : NULL, + VEXPRESS_FLASH_SECT_SIZE, + VEXPRESS_FLASH_SIZE / VEXPRESS_FLASH_SECT_SIZE, 4, + 0x00, 0x89, 0x00, 0x18, 0)) { + fprintf(stderr, "vexpress: error registering flash 0.\n"); + } + + dinfo = drive_get_next(IF_PFLASH); + if (!pflash_cfi01_register(map[VE_NORFLASH1], NULL, "vexpress.flash1", + VEXPRESS_FLASH_SIZE, dinfo ? dinfo->bdrv : NULL, + VEXPRESS_FLASH_SECT_SIZE, + VEXPRESS_FLASH_SIZE / VEXPRESS_FLASH_SECT_SIZE, 4, + 0x00, 0x89, 0x00, 0x18, 0)) { + fprintf(stderr, "vexpress: error registering flash 1.\n"); + } sram_size = 0x2000000; memory_region_init_ram(sram, "vexpress.sram", sram_size); -- 1.7.5.4
