Hosts the 0x221E linux distro kernel. https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-4.10.y 2016-11-30T19:54:25Z 2016-11-30T19:54:25Z Alexey Brodkin 2016-11-22T11:16:36Z urn:sha1:7badf6fefca8278e749e82411fdb98b123cca50e Up until now we had ARC PGU not enabled in axs10x defconfigs trying to not bloat kernel image again with yet another drivers and subsystems. This change configures ARC PGU (as well as DRM bits it depends on) to be built as a module and so those who need LCD screen to work on axs10x may bundle built .ko files in their target's file-system with help of the following command on host: ------------->8------------- make INSTALL_MOD_PATH=_path_to_target_fs_ modules_install ------------->8------------- and later on target with commands as simple as: ------------->8------------- modprobe adv7511.ko modprobe arcpgu.ko ------------->8------------- get LCD working.

Same kernel would work fine on both, even with embedded DT, assuming the FPGA bitfile configuration is same Suggested-by: Francois Bedard <fbedard@ynopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com> 2016-11-30T19:54:25Z Vineet Gupta 2016-10-31T21:26:41Z urn:sha1:044214200b0b7aa4633d2e93529e55b5ca50a5a5 The original distinction was done as they were developed at different times and primarily because they are specific to UP (RTC) and SMP (GFRC). But given that driver handles that at runtime, (i.e. not allowing RTC as clocksource in SMP), we can simplify things a bit.

Note 1: PCT node was missing for some reason in nsimosci.dts while all other nSIM-related .dts files already had PCT node for quite some time, so adding it now. Note 2: All defconfigs were regenerated with "make savedefconfig" which led to some clean-ups in nsimosci_hs_smp_defconfig: CONFIG_FRAMEBUFFER_CONSOLE=y was removed because it is automatically selected now by DRM.
