| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check the core timer status register (TSR) for watchdog reset, and and set the QRIO's reset reason flag REASON1[0] accordingly.

So, this is the solution. Add a tool to generate the equivalent boards.cfg file based on the latest Kconfig, defconfig and MAINTAINERS. We can keep all the functions of MAKEALL and buildman with it.

Going forward, we use Kconfig for the board configuration. mkconfig will never be used. Nor will include/config.mk be generated. Kconfig must be adjusted for U-Boot because our situation is a little more complicated than Linux Kernel. We have to generate multiple boot images (Normal, SPL, TPL) from one source tree. Each image needs its own configuration input. Usage: Run "make <board>_defconfig" to do the board configuration. It will create the .config file and additionally spl/.config, tpl/.config if SPL, TPL is enabled, respectively. You can use "make config", "make menuconfig" etc. to create a new .config or modify the existing one. Use "make spl/config", "make spl/menuconfig" etc. for spl/.config and do likewise for tpl/.config file. The generic syntax of configuration targets for SPL, TPL is: <target_image>/<config_command> Here, <target_image> is either 'spl' or 'tpl' <config_command> is 'config', 'menuconfig', 'xconfig', etc. When the configuration is done, run "make". (Or "make <board>_defconfig all" will do the configuration and build in one time.) For futher information of how Kconfig works in U-Boot, please read the comment block of scripts/multiconfig.py. By the way, there is another item worth remarking here: coexistence of Kconfig and board herder files. Prior to Kconfig, we used C headers to define a set of configs. We expect a very long term to migrate from C headers to Kconfig. Two different infractructure must coexist in the interim. In our former configuration scheme, include/autoconf.mk was generated for use in makefiles. It is still generated under include/, spl/include/, tpl/include/ directory for the Normal, SPL, TPL image, respectively.

It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having a form of whitelist to check if we know of a CPU core and and obtain CBAR is a bit silly. It doesn't scale (how about A12, A17, as well as other I don't know about?), and is actually a property of the SoC, not the core. So either it works and everybody is happy, or it doesn't and the u-boot port to this SoC is providing the real address via a configuration option. The result of the above is that this code doesn't need to exist, is thus forcefully removed. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| * | ARM: HYP/non-sec: allow relocation to secure RAMMarc Zyngier2014-07-28-140/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current non-sec switching code suffers from one major issue: it cannot run in secure RAM, as a large part of u-boot still needs to be run while we're switched to non-secure. This patch reworks the whole HYP/non-secure strategy by: - making sure the secure code is the *last* thing u-boot executes before entering the payload - performing an exception return from secure mode directly into the payload - allowing the code to be dynamically relocated to secure RAM before switching to non-secure. This involves quite a bit of horrible code, specially as u-boot relocation is quite primitive. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
| * | ARM: HYP/non-sec: add separate section for secure codeMarc Zyngier2014-07-28-1/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In anticipation of refactoring the HYP/non-secure code to run from secure RAM, add a new linker section that will contain that code. Nothing is using it just yet. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
| * | ARM: add missing HYP mode constantMarc Zyngier2014-07-28-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to be able to use the various mode constants (far more readable than random hex values), add the missing HYP and A values. Also update arm/lib/interrupts.c to display HYP instead of an unknown value. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
