The old binding does describe the entire default param RAM (0x3d80 size 0x30). The relocation index is within this param RAM at 0x3dac. So the old binding is enough to allow relocation. The issue today with the driver (hence my first patch) is that the driver reads the relocation index but takes a wrong decision if the index is 0: it assumes that an nul index means that a param RAM shall be allocated, which is wrong. A nul index means that the component doesn't support relocation, so the default param RAM shall be used. The function used for that is supposed to return the index. So when the index is null, I need to calculate it. Now, it can't be the SPI driver by itself that decide if he has to relocate or not. Because it depends whether I need to relocate or not. There is no point in waisting another area of the dualport RAM if I don't need to use SCC2 in a mode that overlaps the SPI parameter RAM. Today on the old MPC8xx, a microcode patch is needed in order to be able to relocate, and relocated address is directly fixed by the code handling the patch (sysdev/micropatch.c). The patch loading function is call very early in the boot process by cpm_reset() which is call by the xxx_setup_arch(). I have two issues with the way it is done today: 1/ the address which in hard coded is the micropatch loading function() is within the area for descripters for the QMC, so I would need to use another address. 2/ for new MPC8xx which don't need microcode patch, I have no way today to relocate. I have the same issue with the relocation of SMC1. Today when we activate SMC1 relocation microcode patch, the loading function has a hard coded relocation area for SMC1 which is the area dedicated to the MPC8xx DSP. It means that I need to change it as I want to use the DSP. Would it be acceptable to define a fixed relocation address in the Kconfig in which we select microcode patch (arch/powerpc/platforms/8xx), instead of having it hardcoded in micropatch.c ? Or maybe it would be possible to select which microcode patch we want/need via the device tree and which address shall be used for relocation ?
