2020-05-18common: Drop net.h from common headerSimon Glass
Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-05-10imx: imx8qm/qxp: check whether m4 partition bootedPeng Fan

For fspi build, we will enable both SPL NOR support and SPL SPI support. SPL will dynamically check the resource owner then select corresponding boot device. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
2020-05-10imx: imx8qm/qxp: Recover SPL data section for partition rebootPeng Fan
When doing partition reboot, the boot image won't be reloaded by ROM, it is just CPU reset to boot entry. The SW has to keep the boot image inside the RAM unchanged. It includes both the TEXT section and DATA section. For SPL, the problem is DATA section will be updated at runtime, so in next partition reboot the data is not same as the initial value from cold boot. If any code depends on the initial value, then it will have problem. This patch introduces a mechanism to recover the data section for partition reboot. It adds a new section in image for saving data section. When from cold boot, the data section will be saved to that new section at SPL early phase. When from partition reboot, the data section will be restored from the new section. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>

2020-05-10imx: imx8qm/qxp: Fix issue in get_effective_memsizeYe Li
When Trusty OS allocates the mem region from 0xfe0000000-0xffffffff, the get_effective_memsize does not return correct memory size. There is a check in get_effective_memsize to find the memreg where the u-boot is running, and return the size of that memreg as the result of get_effective_memsize. When using aligned start, the value is 0x80200000 since it is 2MB aligned. Thus the finding of memreg will fail and return the PHYS_SDRAM_1_SIZE because u-boot text base is 0x80020000. This cause u-boot is relocated to the high memory where has been occupied by Trusty OS.

2020-05-10imx8: Replace SC_R_LAST with SC_R_NONE in DTBLeonard Crestez
We are currently using SC_R_LAST as a marker for imx8 power domain tree nodes without a resource attached. This value is compiled into dtb as part of the linux build and used by uboot. The SC_R_LAST constant changes frequently as SCFW resources are added (by design) and every time we need to update linux and uboot headers together or boot can fail. Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE defined to be 0xFFF0.

These functions relate to memory init so move them into the init header. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-12-02common: Move some cache and MMU functions out of common.hSimon Glass
These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

2019-01-28imx8: cpu: restrict checking ROM passover info for revAPeng Fan
Passover info only for revA. move get_cpu_rev out of CONFIG_CPU to avoid build failure when using get_cpu_rev in SPL. Add a CONFIG_SPL_BUILD for passover usage, no need to execute it again in normal U-Boot stage. Also if still checking passover info in normal U-Boot stage, need to make the passover code executed after arch_cpu_init_dm. So to make it easy and clean, only execute the code for SPL stage.
