* 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 support for coprocessor operationsAmaury Pouly2017-01-24

* 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
* ATJ hwstub make irq based usb driver workMarcin Bukat2016-11-10
| | | | | | | | | | | 0e2b490 introduced rework of usb driver which was broken. It was reverted in f2da975 to restore hwstub functionality on ATJ. This commit reenables usb rework AND fixes remining issues. The problem was with 0 length OUT thransfers. Additionally a few cleanups were made. Change-Id: I529ea9ad6540509e9287ca7e1cd2b44369b03cbb

| | | | | | | | | This reverts commit 0e2b4908d012dbd45a58002774f32b64ea8f83e3. Although I swear it was tested it apparently broke hwstub on atj. I will need to investigate more whats going on. Revert for now. Change-Id: I2ff3adf8c72bb0e53be7d81b975382adfb700eab
* 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/qeditor: add support for atomic read/writesMarcin Bukat2014-11-18
| | | | | | | | | | The current code assumed that READ/WRITE would produce atomic read/writes for 8/16/32-bit words, which in turned put assumption on the memcpy function. Since some memcpy implementation do not always guarantee such strong assumption, introduce two new operation READ/WRITE_ATOMIC which provide the necessary tools to do correct read and write to register in a single memory access.

* utils/hwstub: make stmp stub able to load in a MMU'ed environementAmaury Pouly2014-02-10
| | | | | | | | | In might be useful to load hwstub in an environment with the MMU active, in which case care must be taken on the order in which things are done. Mostly, one should not disable the MMU before moving stuff around. The code assumes the linking address (0 currently) is identity mapped. Change-Id: I8d54ce9e8cadcde2e08990353ca7a46803731ca7
* utils/hwstub: completely rework the protocol, drop unused featuresAmaury Pouly2014-02-10
| | | | | | | | | | | | | | | | | The protocol has evolved a lot during the 2.x.y lifetime, bringing more features which later got unused. This commit removes all the unused stuff and simplifies everything: - drop the feature mask: everything is mandatory or stalled on error - remove the info request and put all static information in standard USB descriptors which are part of the configuration descriptor (and can be retrieved using the standard GetDescriptor request). - remove the USB interface, we had only one anyway - remove all endpoint descriptors - remove the exit/atexit stuff, it never worked as intended anyway - update the hwstub library and make it able to handle any device - update the tools (mostly renaming and removing of code) Change-Id: I1872bba7f4177fc3891180e8f944aab88f5bde31
