20a58ac0d8e09d0bf1a74c6b68fea22784512b51 - arc: introduce separate section for interrupt vector table

Wed, 24 Dec 2014 14:17:11 +0000

arc: introduce separate section for interrupt vector tableEven though existing implementation works fine in preparation tosubmission of ARCv2 architecture we need this change.In case of ARCv2 interrupt vector table consists of just addressesof corresponding handlers. And if those addresses will be in .textsection then assembler will encode them as everything in .text sectionas middle-endian and then on real execution CPU will read swappedaddresses and will jump into the wild.Once introduced new section is situated so .text section remains thefirst which allows us to use common linker option for linking everythingto a specified CONFIG_SYS_TEXT_BASE.Signed-off-by: Alexey Brodkin Signed-off-by: Igor Guryanov List of files: /rk3399_rockchip-uboot/arch/arc/Makefile

4c8c485ad9249e1ca1822474954b78799ca937e9 - arc: introduce "mdbtrick" target

Mon, 29 Dec 2014 12:42:57 +0000

arc: introduce "mdbtrick" targetMetaWare debugger (MDB) is still used as a primary tool for interactionwith target via JTAG. Moreover some very advanced features are not yetimplemented in GDB for ARC (and not sure if they will be implemntedsometime soon given complexity and rare need for those features forcommon user).So if we're talking about development process when U-Boot is loaded intarget memory not by low-level boot-loader but manually through JTAGchances are high developer uses MDB for it.But MDB doesn't support PIE (position-independent executable) - it willrefuse to even start - that means no chance to load elf contents ontarget.Then the only way to load U-Boot in MDB is to fake it by: 1. Reset PIE flag in ELF header This is simpe - on attempt to open elf MDB checks header and if itdoesn't match its expectation refuces to use provided elf. 2. Strip all debug information from elf If (1) is done then MDB will open elf but on parsing of elf's debuginfo it will refuse to process due to debug info it cannot understand(symbols with PIE relocation).Even though it could be done manually (I got it documented quite a whileago here http://www.denx.de/wiki/U-Boot/ARCNotes) having this automatedway is very convenient. User may build U-Boot that will be loaded ontarget via MDB saying "make mdbtrick".Then if we now apply the manipulation MDB will happily start and willload all required sections into the target.Indeed there will be no source-level debug info available. But still MDBwill do its work on showing disassembly, global symbols, registers,accessing low-level debug facilities etc.As a summary - this is a pretty dirty hack but it simplifies life a lotfor us ARc developers.Signed-off-by: Alexey Brodkin Cc: Tom Rini Cc: Wolfgang Denk List of files: /rk3399_rockchip-uboot/arch/arc/Makefile

e19db555b4ac79dafa04cc5ff98bdbff01e19388 - Kbuild: introduce Makefile in arch/$ARCH/

Fri, 21 Nov 2014 22:51:33 +0000

Kbuild: introduce Makefile in arch/$ARCH/Introduce a Makefile under arch/$ARCH/ and include it in thetop Makefile (similar to Linux kernel). This allows furtherrefactoringi like moving architecture-specific code out of globalmakefiles, deprecating config variables (CPU, CPUDIR, SOC) ordeprecating arch/$ARCH/config.mk.In contrary to Linux kernel, U-Boot defines the ARCH variable byKconfig, thus the arch Makefile can only included conditionallyafter the top config.mk.Signed-off-by: Daniel Schwierzeck Acked-by: Masahiro Yamada List of files: /rk3399_rockchip-uboot/arch/arc/Makefile
