Rasmus Villemoes 748da8abb0 imx8: add rom api wrappers ... The ROM API is thoroughly undocumented, but apparently passing the xor of the real arguments as an extra argument is required [1]. Also, we need to do the "save gd/restore gd" dance. These are both error-prone, and lead to a lot of code duplication. Since both imx8m[np] and imx8ulp SOCs have this, add a separate translation unit which is included precisely when the new CONFIG_IMX8_ROMAPI symbol is set, which provide convenience wrappers that take care of computing the xor value as well as doing the gd dance, and that thus have a more intuitive API. Subsequent patches will make use of these to reduce boilerplate. [1] One wonders, for example, if the check is only applied to the lower 32 bits, or if we're implicitly relying on all 64-bit pointer values we're passing effectively have 0 in the upper 32 bits.
