board: axs10x switch serial port and Ethernet to driver model

2015-11-17T21:39:22Z

With this change Synopsys DesignWare SDP board is switched to driver model for both serial port (serial_dw) and Ethernet (Designware GMAC). This simplifies include/configs/axs101.h and allows for reuse of Linux's Device Tree description. For simplicity Linux's .dts files are not blindly copied but only very few extracts of them are really used (those that are supported in U-Boot at the moment).

arc: add stubs for map_physmem() and unmap_physmem()

2015-11-17T21:38:35Z

Up until now there was no need in those stubs. But since following commit compilation of U-Boot on ARC is broken: ------------------------>8---------------------- commit 7861204c9af7fec1ea9b41541c272516235a6c93 Author: Stephen Warren Date: Sat Oct 3 13:56:46 2015 -0600 itest: make memory access work under sandbox itest accesses memory, and hence must map/unmap it. Without doing so, it accesses invalid addresses and crashes. Signed-off-by: Stephen Warren Reviewed-by: Simon Glass ------------------------>8---------------------- That's because CMD_ITEST is enabled by default in common/Kconfig and now map_physmem()/unmap_physmem() is used there. So this patch adds missing stubs for ARC. Signed-off-by: Alexey Brodkin Reviewed-by: Simon Glass Cc: Stephen Warren

Various Makefiles: Add SPDX-License-Identifier tags

2015-11-10T14:19:52Z

After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag. Cc: Kate Stewart Signed-off-by: Tom Rini

arc: Use the generic bitops headers

arc: make AXS101 default platform

2015-09-07T10:38:24Z

This fixes building in automated flow that doesn't use defconfigs. See discussion on that topic here: http://patchwork.ozlabs.org/patch/502558/ See similar patches for other architectures/platforms here: [1] http://git.denx.de/?p=u-boot.git;a=commit;h=ff560a13056a565a4e9ce1761bd04276a3cace88 [2] http://git.denx.de/?p=u-boot.git;a=commit;h=589907e2c187ec69b351c38ccda36730d25ab5d6 And while at it add missing shell prompt to axs103.

arc: significant cache rework

2015-07-01T14:17:27Z

[1] Align cache management functions to those in Linux kernel. I.e.: a) Use the same functions for all cache ops (D$ Inv/Flush) b) Split cache ops in 3 sub-functions: "before", "lineloop" and "after". That way we may re-use "before" and "after" functions for region and full cache ops. [2] Implement full-functional L2 (SLC) management. Before SLC was simply disabled early on boot. It's also possible to enable or disable L2 cache from config utility. [3] Disable/enable corresponding caches early on boot. So if U-Boot is configured to use caches they will be used at all times (this is useful in partucular for speed-up of relocation). Signed-off-by: Alexey Brodkin

arc: implement slave cores kick-start for Linux kernel

2015-07-01T14:17:27Z

With new SMP-enabled CPUs with ARC HS38 cores and corresponding support in Linux kernel it's required to add basic SMP support in U-Boot. Currently we assume the one and only core starts execution after power-on. So most of things in U-Boot is handled in UP mode. But when U-Boot is used for loading and starting Linux kernel right before jumping to kernel's entry point U-Boot: [1] Sets all slave cores to jump to the same address [kernel's entry point] [2] Really starts all slav cores In ARC's implemetation of SMP in Linux kernel all cores are supposed to run the same start-up code. But only core with ID 0 (master core) processes further while others are looping waiting for master core to complete some initialization. That means it's safe to un-pause slave cores and let them execute kernel - they will wait for master anyway. Signed-off-by: Alexey Brodkin Cc: Vineet Gupta

Move default y configs out of arch/board Kconfig

2015-06-26T02:17:55Z

Some archs/boards specify their own default by pre-defining the config which causes the Kconfig system to mix up the order of the configs in the defconfigs... This will cause merge pain if allowed to proliferate. Remove the configs that behave this way from the archs. A few configs still remain, but that is because they only exist as defaults and do not have a proper Kconfig entry.
