support/testing/tests/boot: new test cases for Grub This commit adds four test cases for Grub: - Grub i386 legacy BIOS - Grub i386 UEFI - Grub x86-64 UEFI - Grub AArch64 UEFI There is some overlap with the ISO9660 filesystem test cases, some of which use Grub, but we found it relevant to have separate test cases for Grub, which were useful to test Grub in non-ISO9660 situations. The Grub ARM UEFI case is not tested, as it requires Grub to be chain-loaded by U-Boot. Implementing this test case is left as an exercise for the reader.

support/testing: use Nehalem cpu emulation for TestGrubX8664EFI In commit 7e0e6e3b8618 (toolchain/toolchain-external/toolchain-external-bootlin: update to 2023.11-1) the TestGrubX8664EFI fails with this error: # efivar -l traps: efivar[86] trap invalid opcode ip:7fc187f4c7f4 sp:7fff9bbaa930 error:0 in libefivar.so.1.38[7fc187f4c000+16000] Illegal instruction This error can be reproduced by installing other packages like "file". The 2023.11-1 Bootlin toolchains are built for a corei7 CPU [0], which is in fact a Nehalem CPU; we switched to the new names in commit 653fa001f304 (arch/Config.in.x86: add "newer" names for several Intel x86 CPU variants). This means that the Bootlin toolchains may use Nehalem-specific instructions. The TestGrubX8664EFI test is also setup for BR2_x86_corei7, so our executables will also contain Nehalem instructions. However, the default Qemu x86_64 is not guaranteed to emulate all the instructions specific to Nehalem, causing runtime issues as reported above. A similar issue has been fixed in toolchain-builder by adding Nehalem cpu emulation on the qemu command line [0].
