2017-04-25nwztools/database: misc improvementsIgor Skochinsky7-29/+314
* make gen_db.py work on Windows/Python 2 - use hashlib module instead of md5sum, also don't rely on / for file path matching - don't use 'file' for a variable name * fix parse_nvp_header.sh for older kernels pre-emmc kernel sources use a slightly different #define format; adjust regexp to catch it. * add nwz-x1000 series NVP layout (from icx1087_nvp.h) some new tags have no description, alas the driver doesn't have them :/ * minor fixes to nvp/README fixed typos/wording Change-Id: I77d8c2704be2f2316e32aadcfd362df7102360d4

2017-02-04regtools/qeditor: replace deprecated QStyleOptionViewItemV4Amaury Pouly2-5/+5
...by QStyleOptionViewItem. Yes Qt got it right, in 5.7 they deprecated QStyleOptionViewItemV4 and recommend using QStyleOptionViewItem which contains less fields except on newer Qt where it contains all fields.

Add lua code to check whether ei/di and ext instructions are supported. This is unclear since xburst is somewhere between mips32r1 and mips32r2. Details results are below, but in summary: they don't work (ei has no effect, di/ext cause illegal instruction exceptions) > ./hwstub_shell -q -b -e 'require("jz/misc"); JZ.misc.enable_sram()' \ -f lua/xburst.lua -e "XBURST.test_ext_inst(0xb32d0000)" [...] Selecting soc jz4760b.

2017-01-24hwstub: rewrite exception catchingAmaury Pouly10-3269/+125
Since we can catch exceptions like data aborts on read/write, it takes very little to also catch exceptions in calls. When extending this with the catching of illegal instructions, the call instruction now becomes much more robust and also for address and instruction probing. Since we can catch several types of exception, rename set_data_abort_jmp to set_exception_jmp. At the same time, simplify the logic in read/write request handlers. Also fix a bug in ARM jump code: it was using stmia r1, {..., pc} as if pc would get current pc + 8 but this is actually implementation defined on older ARMs (typically pc + 12) and deprecated on newer ARMs, so rewrite the code avoid that. The set_exception_jmp() function now also reports the exception type. Change-Id: Icd0dd52d2456b361b27c4776be09c3d13528ed93
2017-01-24hwstub/jz460b: implement exception recoveryAmaury Pouly4-1/+106
Now that we now that jz4760b implements EBASE, we can use it to rebase exceptions to use a k1seg address, that maps to the physical address of the TCSM0. It requires to enable HAB1 to have this translation. This most the most inefficient way to access tighly coupled memory ever, but it works. Change-Id: I894ca929c9835696102eb2fef44b06e6eaf96d44

2017-01-24hwstub: add various jz stuff and xburst testsAmaury Pouly2-0/+281
The JZ misc allows to enable and test SRAM. The XBurst code uses the coprocessor interface to analyse the cpu. It also provides a test platform for various features like EBASE and exceptions. I was able to test and confirm that on jz4760b (thus xburst), EBASE works (but top 2 bits are not controllable and always 01). The processor claims to support vector interrupts but this is untested. The values in ConfigX are not to be trusted blindly, clearly some are wrong. I tried to use the JZ4780 Config7 "ebase gate" to change bit 30 of EBASE but it does not work, which suggests that JZ480 uses a newer version of XBurst. Detailled log below: > ./hwstub_shell -q -f lua/xburst.lua -e "XBURST.init()" [...] XBurst: PRId: 0x2ed0024f CPU: JZ4760(B) Config: 0x80000483 Architecture Type: MIPS32 Architecture Level: Release 2 (or more) MMU Type: Standard TLB Config1: 0x3e63318a MMU Size: 32 ICache Sets per way: 128 Ways: 4 Line size: 32 DCache Sets per way: 128 Ways: 4 Line size: 32 FPU: no Config2: 0x80000000 Config3: 0x20 Vectored interrupt: yes Config7: 0x0 > ./hwstub_shell -q -e 'require("jz/misc"); JZ.misc.enable_sram()' \ -f lua/xburst.lua -e "XBURST.test_ebase(0x80000000);XBURST.test_ebase(0xb32d0000) [...] Testing EBASE...

2017-01-24hwstub: add the possibility to flush caches before execAmaury Pouly4-1/+45
This is needed on the jz4760b because if some data is loaded to DRAM, then it is cached and a disaster lurks if dcaches/icache are not flushed. Targets that needs this must define CONFIG_FLUSH_CACHES in target-config.h and implement target_flush_caches(). Currently MIPS has some generic code for mips32r1 that requires to define {D,I}CACHE_SIZE and {D,I}CACHE_LINE_SIZE in target-config.h Change-Id: I5a3fc085de9445d8c8a2eb61ae4e2dc9bb6b4e8e

The stub is quite versatile: it can be loaded using bootrom or another other means (like factory boot on Fiio X1). It relocates itself to TCSM0 and provides basic functionality (it does not recover from failed read/writes at the moment). Change-Id: Ib646a4b43fba9358d6f93f0f73a5c2e9bcd775a7

2017-01-24regtools: add JZ4760B descriptionAmaury Pouly1-0/+13645
This is a register description file for the JZ4760B. There are several details worth noticing: - it was obtained by gathering information from several sources/headers, but since there are inconsistencies between them about the exact differences between JZ4760 and JZ4760B, this file probably contains some errors - the register names are not the same as the manual ones (which are not the same as the one in the headers anyway): I dropped the "R" suffix on most registers because it's redundant - Ingenic likes to have read-only registers and then set/clr registers, with very confusing names like DIR/DIRS/DIRC: in the file, the set/clr registers are described as set/clr variants of the original register - Parts of the description were obtained programmatically, which explains why there are empty nodes or partially undocumented registers Change-Id: I8da1d61e172e932e1a4a58ac0a5008f02b1751be

2017-01-16imxtools/sbtools: rework cryptographyAmaury Pouly9-318/+171
It was a mess, a mix of crypto_* and cbc_mac calls. I made everything call crypto functions, and also separate key setup from cryptographic operations, this will be useful to speed up the code in the upcoming commits. Drop support for "usbotp" key, since the crypto code for that was never mainlined and we can always get the keys from a device as long as we have code execution (using the DCP debug registers).

2017-01-16imxtools: rework sb file productionAmaury Pouly2-73/+82
The old code had some annoying way of dealing with padding by adding explicit instructions to the stream, which is 1) ugly 2) not in par with freescale tools. The trick, which this new version implements, is to put the useful length of the section in the section header, and the actual (with padding) length in the boot tag. This way the tools can just ignore padding instruction by reading the section header, and the bootloader can still load the image because it uses the boot tags. Also correctly handle the case where the first section does not start right after the header (there is a bug in freescale tools for this case by the way). There is an ambiguity in the way the padding instructions should be encrypted: the bootloader should logically treat them as regular instruction of the section stream, but it appears the freescale tools do not generate them as part of the stream and instead encrypt them like boot tags, which is stupid because there is no way the bootloader could decrypt them, and anyway we don't care because the bootloader doesn't decrypt them at all.
