[U-Boot] RFC, dm: devices and device_info platdata manual relocation

Hi all,

i have seen, updating u-boot in NOR parallel flash, that the U_BOOT_DEVICE structure "platdata" ptr is still pointing to flash, so the update (rewriting flash) die silently and fails.

I have found a workaround using misc_init_r that works in my board.c, as below, but i don't like too much the solution:

... #include <dm/platform_data/serial_coldfire.h> ...

DECLARE_GLOBAL_DATA_PTR; ....

int misc_init_r(void) { /* * FIXME: relocation seems not working properly on m68k, * so relocating manually */ struct udevice *dev; int retval;

printf("misc_init_r(): entering\n");

retval = uclass_find_device(UCLASS_SERIAL, 0, &dev);

if (!retval) { printf("misc_init_r(): relocating serial device\n");

dev->platdata += gd->reloc_off; }

return 0; }

static struct coldfire_serial_platdata mcf5307_serial_plat = { .base = CONFIG_SYS_UART_BASE, .port = 0, .baudrate = CONFIG_BAUDRATE, };

U_BOOT_DEVICE(coldfire_serial) = { .name = "serial_coldfire", .platdata = &mcf5307_serial_plat, };

So, i can keep this changes in my board, but, i am wondering if manual-reloc of devices structures is maybe responsibility of drivers/core/root.c, something like

int dm_init(void)

{

..... #if defined(CONFIG_NEEDS_MANUAL_RELOC) fix_drivers(); fix_uclass(); fix_devices(); <------------- #endif

.....

Every comment is welcome.
