[PATCH] MdeModulePkg/PartitionDxe: hack MBR unique signature to zero

by Ryan Harkin

This is a hack and is not intended to go upstream, but will be useful for Linaro's short term goals. Linaro's development boards use SD cards, currently we have a problem where each unique SD card has a different UUID when created with linaro-media-create / linaro-android-media create. This means that no one Boot Device configuration can boot Linaro images without some manual intervention from the user. This hack will zero the signature (UUID) read from the card meaning that all SD cards will appear to be the same card.

[PATCH] Samsung/Arndale: use Linaro default config

by Ryan Harkin

The attached patch will change the default config for the Arndale board so that it boots into a Linaro SD card image. Problem is that a bug [1] prevents the Arndale board booting from a linaro-media-create'd image, so this patch can only sensibly applied after that bug is fixed.

Re: [PATCH] Samsung/Arndale: fix RELEASE build with ARMLINUXGCC

This restriction is violated in almost every case in the files I patched. I merely coded my changes to blend in with the surrounding code, as any good maintenance programmer would do. The coding standard's requirement is, in this case, contrary to commonly accepted coding practice in the industry for the last decade. It really should be removed from the DRAFT standard. The mandatory space between the function name and the opening paren of its argument list needs to go away too: the vast majority of the programmers I've spoken with read that as missing a binary operator between a variable and a parenthized expression. They have to re-read the code several times before it becomes apparent that this is a function call and not a coding error. The existence of documented exceptions (macro definitions, etc.) support the argument that it's a bad practice. Feel free to change the patch as you see fit. I never expected to publish these changes; they were intended only to help me figure out why I couldn't build a standard target in my development environment. Ryan asked for copies so I provided them. -Reece

[PATCH] panda: build.sh: change RELEASE/DEBUG param handling

by Ryan Harkin

The attached patch changes the PandaBoardPkg/build.sh script RELEASE or DEBUG parameter handling. Before this patch, build.sh can be called thus: ./build.sh ./build.sh -b DEBUG ./build.sh RELEASE This patch simplifies the way you pass the debug/release parameter into build.sh so that build scripts can simply pass DEBUG or RELEASE, without having to create a special case to add the "-b". Eg. ./build.sh ./build.sh DEBUG ./build.sh RELEASE

Linaro UEFI 2013.01 released

by Ryan Harkin

Hello all, This month's Linaro UEFI release is special: it's the first release from the new tree, using the new process. The whole thing is documented here; including submission guidelines, release dates, tree locations, build instructions, ...: https://wiki.linaro.org/LEG/Engineering/Kernel/UEFI/ The tree can be found here: http://git.linaro.org/gitweb?p=arm/uefi/uefi-next.git;a=summary The main points about the new tree: - The "master" branch is "long lived", it never gets rebased. - it contains the latest edk2 code from Tianocore - this is taken directly from the Tianocore GIT, so the SHAs match - it contains the latest FatDriver2 from Tianocore - Tianocore does not run a GIT repo for this project - this is taken from the Linaro GIT mirror of the Tianocore SVN - it contains the latest BaseTools from Tianocore - ie. not the version in the edk2 repo but the latest devel code - this is taken directly from the Tianocore GIT, so the SHAs match - branches exist for each sub-tree: - "tianocore-edk2" - "tianocore-edk2-fatdriver2" - "tianocore-edk2-basetools" - The "linaro-tracking" branch is "long lived", it never gets rebased. - it contains the all latest development work from Linaro - currently linaro-uefi-2013.01 - The "linaro-release" branch is "long lived", it never gets rebased. - it contains the latest release from Linaro - currently linaro-uefi-2013.01 - Monthly tracking branches are created - At the start of each month, I will update the master branch from the Tianocore upstreams - It gets tagged as "linaro-base-YYYY.MM" - I will then take a branch from this: the monthly tracking branch - The monthly tracking branch is "long lived", it never gets rebased. - "linaro-tracking-2013.01" is the most recent branch - it is now frozen and the release has been cut - I am about to create the "linaro-tracking-2013.02" branch - Topic branches are rebased each month - All branches for specific topics, e.g., Arndale BSP, get rebased to the monthly tracking branch - Any upstreamed patches are dropped - The patch set is tidied up; any "fix" patches are squashed, etc. - The branch is then merged to the monthly tracking branch - Release Candidates - Once all the topic branches are merged to the monthly tracking branch, tracking gets tagged as a release candidate - "linaro-tracking" is updated to each RC - Patches are accepted via the Boot Architecture mailing list - During the cycle, patches are merged into the relevant topics - When a complete series of patches is merged, a new RC is created. - This is currently ad-hoc and not on a time-table - Each time the tree is updated, a snapshot build is triggered in Linaro's Continuous Integration system, Jenkins. - Builds can be found on snapshots.linaro.org [1] - Release - At the end of the cycle, the monthly tracking branch is frozen - Dated follow linux-linaro - Freeze is the 2nd last Thursday of the month, eg. 21st Feb 2013 - Only urgent fixes can be accepted - Release Candidate builds are made on the following Monday, eg. 25th Feb 2013 - The release happens the last Thursday of the month, eg, 28th Feb 2013 - Release binaries are copied to releases.linaro.org [2] - The released code is copied to the uefi.git tree [3] - some users may find a problem using a tree where some branches are rebased - uefi.git has only 1 branch and is never rebased - the SHA ids do not match uefi-next.git I see this process as "in progress" and open to suggestions and change. Regards, Ryan.

Hello, Question about SctPkg.

by Steven Kinney

I am porting the UEFI ARM SctPkg into the core UEFI and I am running into a problem; Linux Host. The BuildSct.sh is trying to copy a utility called GenBin_lin{64, 32}, in my case GenBin_lin_64, that should be populated within ~/SctPkg/Tools/Bin/. My compilation executes fine, but I am unable to generate a binary because of the lacking GenBin for Linux; there is a GenBin.exe populated for a Windows Host. Anyone have any advise. Much appreciated, Steve
