2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.

We don't always want to use ARMv7 code when building for ARM, so we should separate out the ARMv7 code so it can be excluded, and also make it possible to include code for some other version of the architecture instead, all per build component for cases where we need more than one architecture version at a time. The tegra124 bootblock will ultimately need to be ARMv4, but until we have some ARMv4 code to switch over to we can leave it set to ARMv7.

2014-09-04cbfstool:linux_trampoline: config CS and DS segment descriptorsCurt Brune
The Linux trampoline code does not set up the segment descriptors for __BOOT_CS and __BOOT_DS as described in the Linux kernel documentation: ... a GDT must be loaded with the descriptors for selectors __BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat segment; __BOOT_CS must have execute/read permission, and __BOOT_DS must have read/write permission; This is not a problem when launching a Linux payload from coreboot, as coreboot configures the segment descriptors at selectors 0x10 and 0x18. Coreboot configures these selectors in the ramstage to match what the Linux kernel expects (see coreboot/src/arch/x86/lib/c_start.S). When the cbfs payload is launched in other environments, SeaBIOS for example, the segment descriptors are configured differently and the cbfs Linux payload does not work. If the cbfs Linux payload is to be used in multiple environments should the trampoline needs to take care of the descriptors that Linux requires. This patch updates the Linux trampoline code to configure the 4G flat descriptors that Linux expects. The configuration is borrowed from the descriptor configs in coreboot/src/arch/x86/lib/c_start.S for selectors 0x10 and 0x18. The linux_trampoline code is slightly refractored by defining the trampoline entry address, 0x40000, as TRAMPOLINE_ENTRY_LOC. This definition is moved into a separate header file, linux_trampoline.h. This header file is now included by both the trampoline assembly language code and the trampoline loader C code. The trampoline assembly language code can now use TRAMPOLINE_ENTRY_LOC as scratch space for the sgdt CPU instruction. Testing Done: Verified the Linux payload is booted correctly in the following environments: 1. Coreboot -> Linux Payload 2. Coreboot -> SeaBIOS -> Linux Payload: (previously did not work) Change-Id: I888f74ff43073a6b7318f6713a8d4ecb804c0162 Signed-off-by: Curt Brune <curt@cumulusnetworks.com> Reviewed-on: http://review.coreboot.org/6796 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Ronald G.

2014-08-27rmodtool: correct final memory size calculationAaron Durbin
Apparently when I originally wrote this I confused myself to no end. The code/data of an rmodule has a set memory size which is associated with the .payload section. The relocation entries may increase the overall footprint of the memory size if the rmodule has no bss but a lot of relocations. Therefore, just compare relocation entries size plus the file size of the .payload section with the memory size of the paylod section. The .empty section is added only when we have not met the final target size.

2014-02-02cbfstool: add code to serialize the header using the new xdr functionsRonald G. Minnich
This change adds a header serialization function. Programmers can thus just set up a header as needed, without worrying about forgetting if and how to use the [hn]to[hn]* functions. In the long term, we will work to remove swab.h, i.e. we need to get to the point where programmers don't have to try to remember [hn]to[nh]* and where it goes. To date, even the best programmers we have have made an error with those functions, and those errors have persisted for 6 or 7 years now. It's very easy to make that mistake.

2014-02-02Add section header parsing and use it in the mk-payload stepRonald G. Minnich
This completes the improvements to the ELF file parsing code. We can now parse section headers too, across all 4 combinations of word size and endianness. I had hoped to completely remove the use of htonl until I found it in cbfs_image.c. That's a battle for another day. There's now a handy macro to create magic numbers in host byte order. I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe we can use it for the others too, but this is sensitive code and I'd rather change one thing at a time. To maximize the ease of use for users, elf parsing is accomplished with just one function: int elf_headers(const struct buffer *pinput, Elf64_Ehdr *ehdr, Elf64_Phdr **pphdr, Elf64_Shdr **pshdr) which requires the ehdr and pphdr pointers to be non-NULL, but allows the pshdr to be NULL. If pshdr is NULL, the code will not try to read in section headers. To satisfy our powerful scripts, I had to remove the ^M from an unrelated microcode file. BUG=None TEST=Build a peppy image (known to boot) with old and new versions and verify they are bit-for-bit the same.
