* ARM: i.MX: external NAND boot: Fix passing boarddataSascha Hauer2020-02-191-5/+18
| | | | | | | | | | | | | | | | | | | | | | | | We used to pass a device tree pointer to imx*_barebox_boot_nand_external(). This no longer works since we compile barebox with -fPIE. The problem is that we only have the first 2KiB of the image available when we start from NAND. The pointer to the device tree is not valid yet. This hasn't been a problem because the pointer is only used later when we have the full image in SDRAM. With -fPIE though the actual pointer is derived indirectly through another pointer, and that pointer to the pointer is also not valid which causes an invalid pointer to the device tree later. This is solved by splitting the NAND boot functions up into two functions. With imx*_nand_relocate_to_sdram() the board code relocates the image out of the NFC SRAM into SDRAM. From that point on the device tree pointer can be accessed and the board can load the image using imx*_nand_load_image() and can afterwards pass control to barebox passing whatever device tee pointer it likes.

* ARM: i.MX Phytec phycard i.MX27: replace __naked with noinlineSascha Hauer2020-02-191-1/+1
| | | | | | | | | phytec_phycard_imx27_common_init() doesn't need to be __naked, because the stack has already been setup. What we want to have though is the noinline attribute to make sure phytec_phycard_imx27_common_init() is indeed a separate function which is called with initialized stack.

* ARM: i.MX Phytec phycard i.MX27: get fdt in common init functionSascha Hauer2020-02-191-13/+8
| | | | | | | No need to get the fdt pointer in the entry functions, we can do this later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: Cleanup stack offset cargo cultSascha Hauer2019-09-091-2/+2
| | | | | | | | | Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16 bytes from the stack top. This is unnecessary as on ARM we have a stack that decrements before storing values. Substracting this offset probably goes back to the U-Boot version we forked from. Stop this now.

* pinctrl: i.MX iomux-v1: Make base address initialization unnecessarySascha Hauer2019-08-141-3/+3
| | | | | | | | | | | | So far we have imx_gpio_mode() to configure a pinmux entry for the older i.MX pinmuxes. For this to work imx_iomuxv1_init() must be called beforehand to configure the base address. Simplify this by introducing SoC specific variants of imx_gpio_mode() which also pass the base address. This makes initialization of the base address unnecessary and the functions usable for PBL. Consequently also compile the code for PBL. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* phycard-imx27: add support for 64MB RAM variantsBaeuerle, Florian2018-12-101-11/+41
| | | | | | | | | Some older pca100 boards were available with 64MB RAM. The chips require a slightly different sdram controller initialization. Support this by building bootloader images for both variants. Signed-off-by: Florian Bäuerle <florian.baeuerle@allegion.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: return positive offset in get_runtime_offset()Sascha Hauer2018-03-211-1/+1
| | | | | | | | | | | When we are linked at 0x0 and running at 0x01000000 then get_runtime_offset() should return 0x01000000 and not 0xff000000. This makes get_runtime_offset() more consistent and better understandable. This was tested on a Freescale i.MX53 Quickstart board. Additionally relocate_to_adr() was tested since that is normally not called. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
