* sandbox: retire CONFIG_LINUX symbol in favor of CONFIG_SANDBOXAhmad Fatoum2020-11-275-10/+6
| | | | | | | | | | | | | 5211e428cbab ("image: Convert the IH_... values to enums") removed the IH_ARCH_LINUX enumeration value leading to breakage of sandbox configurations that enable bootm. Instead of reinstating IH_ARCH_LINUX, just use IH_ARCH_SANDBOX and remove mention of CONFIG_LINUX altogether, it's always true anyway when CONFIG_SANDBOX is true.

* usbgadget: autostart: don't print error on repeated nv.usbgadget.autostart=1Ahmad Fatoum2020-11-241-2/+8
| | | | | | | | | | | | | | | | | | | | | | nvvar_add results in two calls to dev_set_param: - once when the existing global variable is found and set - once more when setting the nv variable This results in an annoying but ultimately harmless message on startup: ERROR: USB multi gadget already registered ERROR: failed to create nv variable usbgadget.autostart: Device or resource busy Avoid this by ignoring usbgadget.autostart=1 after it succeeded once. This issue should only affect $global.usbgadget.autostart, because all other global variables are "simple" meaning that they have no setters triggered.

* Documentation: state: clarify how to access state device parametersAhmad Fatoum2020-11-131-3/+3
| | | | | | | | | | | | Users may be inclined to use hyphens in state variable names as this is customary for device tree nodes. Such variables can't be read with $state.example-variable or written with state.example-variable=, because it's incompatible with Hush. Adjust the documentation to nudge users into the correct direction (${state.example-variabe} and setenv) Suggested-by: Matthias Fend <Matthias.Fend@wolfvision.net> Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* doc: add note about characters like hyphens in variable namesAhmad Fatoum2020-11-131-1/+8
| | | | | | | | | | | | | | The mismatch between the allowed characters in shell variables and device parameters is a common pitfall, especially because device tree node names often have hyphens in them, which is disallowed by hush. While such variables can be read by the ${variable-example}, setting them is only possible with the setenv command. Reflect this in the documentation.

| | | | | | | | | | | | copy_spare used to take a mtd_info, but since 5f605dc6168c ("mtd: nand: Pass struct nand_chip around") it now takes a nand_chip. 3588d40c5385 ("mtd: nand-imx: repair reading the oob area") was drafted in parallel and still passes a mtd_info.

| | | | | | | | | | | | 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 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>
