So I know Albert was tacking a PR today and then ran into a bug with his Thumb-1 patchset. If they aren't in that PR then yes, I'll review/ack them but I suspect / hope Albert is taking a look and got side-tracked by the bug he found. > > Thanks, > > TomW > > > -----Original Message----- > > From: Tom Warren > > Sent: Friday, November 06, 2015 9:32 AM > > To: 'Albert ARIBAUD' <albert.u.b...@aribaud.net>; 'Stephen Warren' > > <swar...@wwwdotorg.org>; Tom Rini (tr...@konsulko.com) > > <tr...@konsulko.com> > > Cc: 'u-boot@lists.denx.de' <u-boot@lists.denx.de>; 'Simon Glass' > > <s...@chromium.org>; Stephen Warren <swar...@nvidia.com>; Thierry Reding > > <tred...@nvidia.com>; 'York Sun' <york...@freescale.com>; 'Michal Simek' > > <michal.si...@xilinx.com>; 'tomcwarren3...@gmail.com' > > <tomcwarren3...@gmail.com> > > Subject: RE: [U-Boot] [PATCH 1/4] armv8: enable compilation with > > CONFIG_SYS_NONCACHED_MEMORY > > > > Albert, > > > > Ping! > > > > > -----Original Message----- > > > From: Tom Warren > > > Sent: Tuesday, November 03, 2015 12:19 PM > > > To: 'Albert ARIBAUD' <albert.u.b...@aribaud.net>; 'Stephen Warren' > > > <swar...@wwwdotorg.org>; Tom Rini (tr...@konsulko.com) > > > <tr...@konsulko.com> > > > Cc: 'u-boot@lists.denx.de' <u-boot@lists.denx.de>; 'Simon Glass' > > > <s...@chromium.org>; Stephen Warren <swar...@nvidia.com>; Thierry > > > Reding <tred...@nvidia.com>; 'York Sun' <york...@freescale.com>; 'Michal > > Simek' > > > <michal.si...@xilinx.com>; 'tomcwarren3...@gmail.com' > > > <tomcwarren3...@gmail.com> > > > Subject: RE: [U-Boot] [PATCH 1/4] armv8: enable compilation with > > > CONFIG_SYS_NONCACHED_MEMORY > > > > > > Albert, > > > > > > > -----Original Message----- > > > > From: Tom Warren > > > > Sent: Tuesday, October 27, 2015 1:39 PM > > > > To: 'Albert ARIBAUD' <albert.u.b...@aribaud.net>; Stephen Warren > > > > <swar...@wwwdotorg.org> > > > > Cc: u-boot@lists.denx.de; Simon Glass <s...@chromium.org>; Stephen > > > > Warren <swar...@nvidia.com>; Thierry Reding <tred...@nvidia.com>; > > > > York Sun <york...@freescale.com>; Michal Simek > > > > <michal.si...@xilinx.com> > > > > Subject: RE: [U-Boot] [PATCH 1/4] armv8: enable compilation with > > > > CONFIG_SYS_NONCACHED_MEMORY > > > > > > > > Albert, > > > > > > > > > -----Original Message----- > > > > > From: Albert ARIBAUD [mailto:albert.u.b...@aribaud.net] > > > > > Sent: Wednesday, October 21, 2015 11:26 PM > > > > > To: Stephen Warren <swar...@wwwdotorg.org> > > > > > Cc: u-boot@lists.denx.de; Simon Glass <s...@chromium.org>; Tom > > > > > Warren <twar...@nvidia.com>; Stephen Warren > > <swar...@nvidia.com>; > > > > > Thierry Reding <tred...@nvidia.com>; York Sun > > > > > <york...@freescale.com>; Michal Simek <michal.si...@xilinx.com> > > > > > Subject: Re: [U-Boot] [PATCH 1/4] armv8: enable compilation with > > > > > CONFIG_SYS_NONCACHED_MEMORY > > > > > > > > > > Hello Stephen, > > > > > > > > > > On Wed, 21 Oct 2015 10:35:59 -0600, Stephen Warren > > > > > <swar...@wwwdotorg.org> wrote: > > > > > > On 10/05/2015 12:08 PM, Stephen Warren wrote: > > > > > > > From: Stephen Warren <swar...@nvidia.com> > > > > > > > > > > > > > > The implementation of noncached_init() uses define > > > > MMU_SECTION_SIZE. > > > > > > > Define this on ARM64. > > > > > > > > > > > > > > Move the prototype of noncached_{init,alloc}() to a location > > > > > > > that doesn't depend on !defined(CONFIG_ARM64). > > > > > > > > > > > > > > Note that noncached_init() calls > > > > > > > mmu_set_region_dcache_behaviour() which relies on something > > > > > > > having set up translation tables with 2MB block > > > > > size. > > > > > > > The core ARMv8 MMU setup code does not do this by default, but > > > > > > > currently relies on SoC specific MMU setup code.
