2016-07-14target-xtensa: xtfpga: fix FLASH interface widthMax Filippov
FLASH chip on XTFPGA boards is connected with 16-bit-wide interface. Latest U-Boot can see the difference and does not work correctly with 32-bit-wide interface. Set FLASH chip 'width' property to 2. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2016-07-12OpenBIOS: switch over to official OpenBIOS git repoMark Cave-Ayland
This update should preserve git history, and switches git.qemu-project.org over to be a mirror of the new official git repo hosted at https://github.com/openbios from a git-svn import of the old coreboot SVN repository. All prior history from the SVN repository should still be preserved (i.e. commit hashes are the same for historical commits). No other source changes are made by this commit since both the old and new HEADs contain the same source tree (albeit with difference metadata) whilst the previous git-svn HEAD can be retrieved via the svn-head branch.

2016-07-12target-sparc: Use explicit writes to cpu_fsrRichard Henderson
By arranging for explicit writes to cpu_fsr after floating point operations, we are able to mark the helpers as not writing to tcg globals, which means that we don't need to invalidate the integer register set across said calls.

2016-07-12target-sparc: Store %asi in TB flagsRichard Henderson
Knowing the value of %asi at translation time means that we can handle the common settings without a function call. The steady state appears to be %asi == ASI_P, so that sparcv9 code can use offset forms of lda/sta. The %asi register gets pushed and popped on entry to certain functions, but it rarely takes on values other than ASI_P or ASI_AIUP. Therefore we're unlikely to be expanding the set of TBs created.

2016-07-12target-sparc: Unify asi handling between 32 and 64-bitRichard Henderson

2016-07-12target-sparc: Store mmu index in TB flagsRichard Henderson
Doing this instead of saving the raw PS_PRIV and TL. This means that all nucleus mode TBs (TL > 0) can be shared. This fixes a bug in that we didn't include HS_PRIV in the TB flags, and so could produce incorrect TB matches for hypervisor state. The LSU and DMMU states were unused by the translator. Including them in TB flags meant unnecessary mismatches from tb_find_fast. Tested-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Richard Henderson <rth@twiddle.net>
2016-07-12target-sparc: Remove softint as a TCG globalRichard Henderson
The global is only ever read for one insn; we can just as well use a load from env instead and generate the same code. This also allows us to indicate the the associated helpers do not touch TCG globals. Tested-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Richard Henderson <rth@twiddle.net>

2016-07-12scripts: New clean-header-guards.plMarkus Armbruster
The conventional way to ensure a header can be included multiple times is to bracket it like this: #ifndef HEADER_NAME_H #define HEADER_NAME_H ... #endif where HEADER_NAME_H is a symbol unique to this header. The endif may be optionally decorated like this: #endif /* HEADER_NAME_H */ Unconventional ways present in our code: * Identifiers reserved for any use: #define _FILEOP_H * Lowercase (bad idea for object-like macros): #define __linux_video_vga_h__ * Roundabout ways to say the same thing (and hide from grep): #if !defined(__PPC_MAC_H__) #endif /* !defined(__PPC_MAC_H__) */ * Redundant values: #define HW_ALPHA_H 1 * Funny redundant values: # define PXA_H "pxa.h" * Decorations with bangs: #endif /* !QEMU_ARM_GIC_INTERNAL_H */ The negation actually makes sense, but almost all our header guard #endif decorations don't negate. * Useless decorations: #endif /* audio.h */ Header guards are not the place to show off creativity. This script normalizes them to the conventional way, and cleans up whitespace while there. It warns when it renames guard symbols, and explains how to find occurences of these symbols that may have to be updated manually. Another issue is use of the same guard symbol in multiple headers. That's okay only for headers that cannot be used together, such as the *-user/*/target_syscall.h. This script can't tell, so it warns when it sees a reuse. The script also warns when preprocessing a header with its guard symbol defined produces anything but whitespace. The next commits will put the script to use.
