* ARM: qemu: add support for qemu virt platformRouven Czerwinski2020-11-125-1/+43
| | | | | | | | | | Necessary support to boot barebox on ARM qemu virt platforms. No internal device tree, since it is passed by qemu. Therefore it employs the generic 2nd stage image as the low level code and only adds a virt specific board driver.

* ARM: vexpress: move Options to ARCH_VEXPRESSRouven Czerwinski2020-11-122-9/+5
| | | | | | | | | In preparation for the qemu virt image, move the KConfig options from MACH_VEXPRESS to ARCH_VEXPRESS. Also remove the choice, since we allow multiple boards to be selected with HAVE_PBL_MULTI_IMAGES.

* ARM: layerscape: ppa: Fix use after freeSascha Hauer2020-11-111-0/+1
| | | | | | | | | | | | In of_psci_do_fixup() we want to delete the one job-ring device node which is used by the PPA secure firmware. When we have deleted the node we may not continue the for_each_compatible_node_from() loop, because that would derefence the just deleted node. We only want to delete a single node, so we do not need to continue the loop once we've found the node, so we can fix the issue by breaking out of the loop.

| | | | | | | | | | | | | | | | | | | | | | | | With the previous commit, we now explicitly tell GCC not to optimize constructs like (1 << 31) under assumption that they are undefined anyway. GCC >= 8.0 -fsanitize=undefined should now not warn any longer about (1 << 31) instances, so remove our work around. This reverts commit 55397b9ebe3a21a3aeb6a98131c0991bff0f7123.

This is wrong, the ECC engine does 512 or 1024 bytes per step. Adjust ecc size and step size accordingly. Also, fix ecc strength which was hardcoded to 1.

This patch is huge, but the barebox NAND layer is so far away from the Linux NAND layer that a step by step update would have taken ages. Unlike Linux barebox has functions to mark a block as good. This feature has been preserved. Also barebox used to make NAND write support optional, this feature is lost during the update for the sake of better compatibility to the Linux NAND layer. This patch has been tested: - GPMI aka nand_mxs on i.MX6 - nand_imx on i.MX25 - nand_omap_gpmc on AM335x - atmel_nand on Atmel sama5d3 - nand_denali on SoCFPGA Currently untested: - nand_orion - nand_mrvl_nfc - nand_s3c24xx The nand_denali driver is tested with the update of that driver to Linux-5.9 following in the next patch. I could only test the drivers with the NAND chips found on my boards, so there's still enough room for regressions, especially given that the NAND drivers themselves are mostly not updated. With the NAND layer being up-to-date with Linux it should hopefully be easy to update drivers to their Linux counterpart as well if necessary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the SDRAM is mapped to address 0x0 and an image should be loaded to to the SDRAM without offset, Barebox would normally trap the access as a null pointer. However, since Linux kernel commit cfa7ede20f13 ("arm64: set TEXT_OFFSET to 0x0 in preparation for removing it entirely") no offset is the default for arm64. Therefore, copying the image to 0x0 of the SDRAM is necessary. Disable the zero page trap for copying an image to address 0x0.

However, if the SDRAM starts at address 0x0, this makes the first page of the SDRAM inaccessible and makes it impossible to load images to offset 0x0 in the SDRAM. Trapping NULL pointer dereferences on such systems is still desirable. Therefore, add a function to disable the traps if accessing the zero page is necessary and to re-enable the traps after the access is done. The zero_page_memcpy function simplifies copying to the SDRAM, because this is the most common required functionality, but memtest also accesses the zero page and does not use memcpy.
