It looks quite weird that for non PPC platforms cpu driver for MPC83xx can be selected. That's why define proper dependency. Signed-off-by:

Upstream Linux kernel uses for mpc8548-based PCIe controllers compatible string "fsl,mpc8548-pcie". So change U-Boot fsl PCIe driver and all DTS files to use "fsl,mpc8548-pcie" instead of "fsl,pcie-mpc8548" to be compatible with Linux kernel. Signed-off-by:

Linux P2020 USB kernel driver uses compatible string fsl-usb2-dr-v1.6 and needs more DT properties. Copy P2020 usb@22000 properties from upstream Linux kernel. Signed-off-by:

interrupts property for spi@7000 node is needed for compatibility with Linux kernel. Signed-off-by:
-
Device tree include file p2020-post.dtsi should be included after the board device tree file and overrides settings of the board. So it should not disable some node as board cannot enable it via normal way (it has to enable it after inclusion of p2020-post.dtsi file). Fix it by removal of explicit disable in p2020-post.dtsi file and then remove explicit post-post enable in all P2020 board device tree files. Currently no P2020 board has spi@7000 node disabled.

Linux kernel eSDHC driver for P2020 requires additional compatible string fsl,p2020-esdhc and interrupts property. Add them to p2020-post.dtsi file to make U-Boot board DTS files compatible for Linux kernel. Signed-off-by:

Import pq3-etsec1-timer-0.dtsi device tree include file from upstream Linux kernel for P2020. This allows U-Boot to use P2020 device tree files from upstream Linux kernel which reference ptp_clock@24e00 device. Signed-off-by:

Replace hardcoded boot i2c bus num and address by existing macros when generating env for CONFIG_EXTRA_ENV_SETTINGS. Same macros are used in U-Boot board code when reading information from boot i2c data. Signed-off-by:

Do not stringify env $vscfw_addr two times (once implicitly via string operator "" and second time explicitly via __stringify() macro) and allow to compile U-Boot without CONFIG_VSC7385_ENET (when __VSCFW_ADDR was not defined and so macro name was stringified into CONFIG_EXTRA_ENV_SETTINGS).

Whole section about USB/eLBC configuration seems to be P1020 specific. So add ifdefs to not compile it on other platforms (e.g. P2020). Signed-off-by:
-
Like for first 1G SDRAM map, do not enable Caching-inhibited nor Guarded attribute for second 1G SDRAM mapping. Whole 2G SDRAM should use caches and also allow speculative loading (by not setting Guarded attribute). Also enable Memory Coherency attribute for second 1G SDRAM map. In commit 316f0d0f ("powerpc: mpc85xx: Fix static TLB table for SDRAM") it was enabled for all SDRAM maps on all other boards, just missed this one case. As a last thing, first 1G SDRAM map has wrong comment, so adjust it. Signed-off-by:

When MPC85xx_PMUXCR_SDHC_WP is set then SDHC controller automatically makes inserted SD card readonly if GPIO[9] is active. In some design GPIO[9] pin does not have to be connected to SD card write-protect pin and can be used as GPIO. So do not set MPC85xx_PMUXCR_SDHC_WP bit when GPIO[9] is not used for SDHC_WP functionality. Signed-off-by:

It is too confusing if sections are defined in non-ascending order. Also linker has to go backward and then again forward when generating final binary. To make future changes easier, define all linker sections in ascending order. Signed-off-by:

Linker knows exact size of the image, so there is no need to use CONFIG_SYS_MONITOR_LEN macro (which should be upper limit). Remove usage of CONFIG_SYS_MONITOR_LEN macro to simplify setup. Signed-off-by:

Currently CONFIG_OF_SEPARATE is completely broken and U-Boot for some mpc85xx board (e.g. P2020) has to be compiled with CONFIG_OF_EMBED. Otherwise it crashes during early init. When debug console is enabled and all debug logging options are turned on then U-Boot on P2020 with CONFIG_OF_SEPARATE prints following error: No valid device tree binary found at 110dc300 initcall sequence 110d3560 failed at call 1109535c (err=-1) ### ERROR ### Please RESET the board ### Problem is with appended DTB. When CONFIG_SYS_MPC85XX_NO_RESETVEC is set U-Boot binary image without DTB ends immediately after the .u_boot_list section. At this position is defined _end symbol at which U-Boot expects start of the appended DTB. Problem is that after .u_boot_list section are in linker script defined another sections with 256 byte long padding which are completely empty. During conversion of U-Boot ELF binary to RAW binary u-boot-nodtb.bin, objcopy removes trailing zero padding and therefore DTB is appended at wrong position. Changing alignment from 256 bytes to 4 bytes fixes this issue. And appended DTB is finally at he correct position. With this fix U-Boot on P2020 with CONFIG_OF_SEPARATE option starts working again.

For compatibility with Linux kernel DTS files and also with other U-Boot powerpc DTS files, rename esdhc@2e000 node to sdhc@2e000 in p1020-post.dtsi and p2020-post.dtsi include files. Linux kernel DTS files which include these dtsi files, expect that esdhc node has name sdhc@2e000 and do not work with other node names. Signed-off-by:

P2020 DTS files in upstream Linux kernel use fsl/p2020si-pre.dtsi and fsl/p2020si-post.dtsi include device tree files. Add symlinks for these include device tree files into U-Boot powerpc directory and points them to U-Boot inline device tree files p2020.dtsi and p2020-post.dtsi. This allows to use P2020 DTS files from upstream Linux kernel in U-Boot. Signed-off-by:
