* ARM64: zynqmp: Add support for standard distro boot commandsMichal Simek2016-06-06-64/+71
| | | | | | | | | | | | | Nand and QSPI are not defined now but this will be extended. Based on selected bootmode boot_targets are rewritten. Patch also contains detection if variables are saved. If yes don't rewrite boot_targets variable. Also move variable setup to the end of file because SCSI needs to be defined before others macros are using it.

* ARM64: zynqmp: Remove CONFIG_BOOTP_SERVERIPAlexander Graf2016-06-06-1/+0
| | | | | | | | | | | | | When the CONFIG_BOOTP_SERVERIP option is set, we ignore all dhcp values for the tftp server and use our own serverip and file name instead. This is usually not what we want and I doubt it's set for a good reason on ZynqMP. It definitely hurts if we want to support uEFI PXE boot on it. So just remove the option for now.

* arm: lib: fix push/pop-section directivesStephen Warren2016-06-03-34/+34
| | | | | | | | | | | | | | | | | | | | | | | With the existing code, function symbols are defined in .text, and the body is defined in .text.xxx. This causes (at least some version of) the linker not to emit the function body into the final binary, since it's part of a different section to the symbols being referenced. This of course causes a wide variety of failures. This change moves the push/pop-section directives before the function symbols, and after any relate ENDPROC macro invocations, so that symbols and bodies are all in the "pushed" sections, and thus the function bodies are emitted into the binary. This solves (at least) the boot problems currently seen on Tegra systems that use SPL (i.e. all ARMv7 Tegras).

| * arm: socfpga: improve raw MMC SPL bootSylvain Lesne2016-06-01-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, when booting from MMC (no filesystem), the SPL loaded U-Boot from a fixed offset. It will now load U-Boot from an offset of 256kB (which is 4 times the padded SPL image) in the third partition. This behaviour is similar to what the vendor SPL (based on U-Boot 2013.01) does, and allows to directly 'dd' the u-boot-with-spl.sfp file to the A2 partition.

As per this DM, the PMIC boot voltage can be set to either 1.10V or 1.15V for VD_MPU, and either 1.06V or 1.15V for VD_CORE. While the current values are correct, the latter set of values are the values that are common across all DRA75x, DRA72x SoCs and for all current Silicon revisions. So, update both the MPU and CORE OPP_NOM voltages to 1.15V. The macros are also slightly reorganized so that both the MPU and CORE voltage domain values are defined together.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch decouples U-Boot binary from the toolchain on systems where private libgcc is available. Instead of pulling in functions provided by the libgcc from the toolchain, U-Boot will use it's own set of libgcc functions. These functions are usually imported from Linux kernel, which also uses it's own libgcc functions instead of the ones provided by the toolchain. This patch solves a rather common problem. The toolchain can usually generate code for many variants of target architecture and often even different endianness. The libgcc on the other hand is usually compiled for one particular configuration and the functions provided by it may or may not be suited for use in U-Boot. This can manifest in two ways, either the U-Boot fails to compile altogether and linker will complain or, in the much worse case, the resulting U-Boot will build, but will misbehave in very subtle and hard to debug ways.

This header file contains macros used in libgcc functions in Linux kernel on ARM and will be needed for the libgcc sync. Since unified.h defines the W(instr) macro, we must drop this from the macro from memcpy.S , otherwise this triggers a warning about symbol redefinition. In order to keep the changes to unified.h to the minimum, tweak arch/arm/lib/Makefile such that it defines the CONFIG_ARM_ASM_UNIFIED macro, which places .syntax unified into all of the assembler files. This is mandatory. Moreover, for Thumb2 build, define CONFIG_THUMB2_KERNEL macro if and only if Thumb2 build is enabled. This macro is checked by unified.h and toggles between ARM and Thumb2 variant of the instructions in the assembler source files. Finally, this patch defines __LINUX_ARM_ARCH__=N macro based on the new CONFIG_SYS_ARM_ARCH Kconfig option. This macro selects between more optimal and more dense codepaths which work on armv5 and newer and less optimal codepaths which work on armv4 and possible armv3m. Tegra2 needs the same special handling as it does in arch/arm/Makefile to cater for the arm720t boot core.

* | arm: config: Introduce CONFIG_SYS_ARM_ARCHMarek Vasut2016-06-02-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce new helper Kconfig option, which is automatically set to the version of ARM architecture for which the U-Boot is built. This is useful when selecting tuning options in the libgcc imported from Linux kernel.

| | | | | | | | | | | | | | | | | | | | | | | | Enable support for tiny printf on the omap3_logic board to trim down the SPL size. This makes the SPL actually build again and fit into the SRAM.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a simple version of this function for SPL. It does not check the buffer size as this would add to the code size.
