device-type:imx:allow to use address in uboot env.
We had next changes for i.mx:
MLK-25823 imx8/imx8m: Update kernel load address to 2MB aligned
Since 5.10, kernel has removed the 0x80000 offset requirement to kernel image load address. Using old address like 0x80280000 by booti will introduce a additional copy to 2MB aligned address.
So set default kernel load address to 0x80200000 for iMX8/iMX8ULP, and 0x80400000 for iMX8M. For old kernel, booti will handle the 0x80000 offset by adding a copy.
Another word, for >=5.10 kernel, we need to change loadaddr for kernel address to increase the speed for boot. But looks LAVA just maintain one copy of value, can't distinguish between different uboot settings.
So, we propose this MR which boot from the addr specified in i.mx uboot environment, with this way, we no need to put an eye on later changes, as uboot build will handle the difference between different kernels, or other kinds of address changes.
Still, we will remain the referenced value, e.g. if any community uboot build doesn't have
fdt_addr, etc, they still could boot using NXP referenced address. But, we will just keep/maintain the latest value of
loadaddr etc. Do you think this strategy ok? Please help to comments on this MR, we need your inputs, thanks.
