* hwstub/jz4760b: add lua code to probe for ei/di and ext instructionsAmaury Pouly2017-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hwstub: rewrite exception catchingAmaury Pouly2017-01-24
| | | | | | | | | | | | | | | | | 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
* hwstub/jz460b: implement exception recoveryAmaury Pouly2017-01-24
| | | | | | | | | 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

* hwstub: add various jz stuff and xburst testsAmaury Pouly2017-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hwstub: add the possibility to flush caches before execAmaury Pouly2017-01-24
| | | | | | | | | | 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

* hwstub: add jz4760b stubAmaury Pouly2017-01-24
| | | | | | | | 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

* hwstub: port hwstub_shell to the new libraryAmaury Pouly2016-04-08
| | | | | | | | | | | | | | | Also use this opportunity to cleanup support for multiple devices: the shell now supports dynamic changes in the device and will call init() everytime a new device is selected, to prepare a new environment. The shell now honors register width on register read/write. The shell also provides access to variants as follows by creating a subtable under the register using the variant type in UPPER case and having the same layout as a register. For example if register HW.GPIO.DIR has variants "set" and "clr", those can be used like this: HW.GPIO.DIR.SET.write(0xff) HW.GPIO.DIR.CLR.write(0xff00) Change-Id: I943947fa98bce875de0cba4338e8b7196a4c1165

* hwstub: rewrite and expand libraryAmaury Pouly2016-04-08
| | | | | | | | | | | | | Rewrite the hwstub library in C++, with a clean and modular design. The library was designed from the ground up to be aware of multithreading issues and to handle memory allocation nicely with shared pointers. Compared to the original library, it brings the following major features: - support for JZ boot devices, it is very easy to add support for others - support for network transparent operations (through sockets): both tcp and unix domains are support Change-Id: I75899cb9c7aa938c17ede2bb3f468e7a55d625b4

* hwstub: Add ajt213x lua interface for DSP blockMarcin Bukat2015-11-17
| | | | | | | | | | | | | | | | | | | | | | With this you can upload and run code on DSP core in atj213x. The files can be produced using as2181. You can download this assembler from https://github.com/wodz/as2181 You should use extended mode (-x switch) since DSP core in atj is non standard and uses 24bit operands. PX register has different meaning as well and is used as MSB when loading other registers with immediates (immediate field is 16bit in instruction so to set register to 24bit value you need to store MSB in PX prior to this). MAC MR is 56bit accordingly. HIP interface seems to be mapped at standard addresses (except that regular 218x doesn't have HIP). Have a fun! Change-Id: I9a80ca0dd3718ba8435ae8579bfffa66e067e022
