> Subject: [PATCH] ARM: imx: imx8mn-evk: change environment address
> variables
> 
> Currently the space between kernel_addr_r and the fdt_addr_r is only 32MB.
> To have enought 

s/enought/enough/

space to load kernel images bigger than 32MB change the
> variables to a feasible value.
> 
> The new environment variables layout is based on the scheme from
> "include/configs/ti_armv7_common.h".
> 
> The CONFIG_SYS_LOAD_ADDR value is set to 0x42000000. With that we have
> the same value as for the kernel_addr_r.
