2016-05-25iPod Classic: HW initialization for RBCástor Muñoz
Do not rely on a bootloader initializing the HW, RB initializes and configures GPIO, I2C, and PMU at startup. Change-Id: If7f856b1f345f63de584aa4e4fc22d130cd66c80
2016-05-25iPod Classic: piezo support for bootloaderCástor Muñoz
Low level functions that do not depend on Rockbox kernel, intended to be used by the bootloader, dualboot-installer, RB drivers or other .dfu tools. Change-Id: If80214d26e505265ace19d9704f1e1300f98b2f4

2016-05-25iPod Classic: HW preliminary initialization for bootloaderCástor Muñoz
When the bootloader starts, most of HW never has been initialized. This patch includes all code needed to perform the preliminary initialization on SYSCON, GPIO, i2c, and MIU. The code is based on emCORE and OF reverse engineering, ported to C for readability. Change-Id: I9ecf2c3e8b1b636241a211dbba8735137accd05c
2016-05-25bootloader/common: disable unused broken codeCástor Muñoz
Disable (probably old) broken code, this fixes bootloader builds when ROCKBOX_HAS_LOGF is used. Change-Id: Id0ed2c3368855e2d2d2dbfb18149b9ed81c10b95
2016-05-25regtools: add headergen_v2Amaury Pouly
This new header generator works differently from the previous one: - it uses the new format - the generated macro follow a different style (see below) - the generated macro are highly documented! - it supports SCT-style platform or RMW-style ones Compared to the old style, the new one generate a big set of macros per register/field/enum (loosely related to iohw.h from Embedded C spec). The user then calls generic (names are customizable) macros to perform operations: reg_read(REG_A) reg_read(REG_B(3)) reg_read_field(REG_A, FIELD_X) reg_read_field(REG_B(3), COOL_FIELD) reg_write(REG_A, 0x42) reg_write_field(REG_A, FIELD_X(1), FIELD_Y(3), IRQ_V(FIQ)) reg_write_fielc(REG_B(3), COOL_FIELD_V(I_AM_COOL), BLA(42)) the following use RMW or SET/CLR variants, depending on target: reg_set_field(REG_A, FLAG_U, FLAG_V) reg_clr_field(REG_A, FIELD_X, FIELD_Y, IRQ) reg_clr_field(REG_B(3), COOL_FIELD, BLA) the following does clear followed by set, on SET/CLR targets: reg_cs(REG_A, 0xff, 0x42) reg_cs(REG_B(3), 0xaa, 0x55) reg_cs_field(REG_A, FIELD_X(1), FIELD_Y(3), IRQ_V(FIQ)) reg_cs_field(REG_B(3), COOL_FIELD_V(I_AM_COOL)) The generator code is pretty long but has lots of documentation and lots of macro names can be customized.

2016-05-15iPod Classic: modify USB storage read/write buffers sizeCástor Muñoz
The write buffer size is undefined to use the default 24Kb. size defined (and recomended) in usb_storage.c, the read buffer size is also decremented to 24 Kb. USB sequential read and write benchmarks using diskdump are now 8-9% faster. Change-Id: Ia7c9f77b57c8ca5b566b508efffbd713d1587acf

2016-05-15iPod Classic: optimize UDMA timming for ATA drivesCástor Muñoz
This patch optimizes UDMA timings to increase write transfer rate on ATA bus, these transfers are clocked by HCLK, tDVS+tDVH is modified to decrease Tcyctyp (typical write cycle period). This is not overclocking, we meet the ATA standar, the settings used by OF are not well optimized for each UDMA mode, we will never know but probably this was due some documentation issue. ATA_UDMA_TIME register is documented on s3c6400 datasheet, information included in s5l8700 datasheet is wrong or not valid for s5l8702. From ATA specs, (Minimum, Maximum) values in nanoseconds: UDMA 0 UDMA 1 UDMA 2 UDMA 3 UDMA 4 tACKENV (20, 70) (20, 70) (20, 70) (20, 55) (20, 55) tRP (160, --) (125, --) (100, --) (100, --) (100, --) tSS (50, --) (50, --) (50, --) (50, --) (50, --) tDVS (70, --) (48, --) (31, --) (20, --) (6.7, --) tDVH (6.2, --) (6.2, --) (6.2, --) (6.2, --) (6.2, --) tDVS+tDVH (120, --) (80, --) (60, --) (45, --) (30, --) Tcyc = tDVS+tDVH WR[bytes/s] = 1/Tcyc[s] * 2[bytes] On Classic (boosted): HClk = 108 MHz. -> T = ~9.26 ns.

The real HDD write speed is limited by the internal transfer rate (depends on cilinder, for the MK1634GAL it is 276 to 573 Mbits/s). Sequential write benchmark using diskdump on USB are ~8% faster. - Read transfers are clocked by the device, it depends on UDMA mode selected and are not affected by HClk or ATA_UDMA_TIME settings. Read-from-cache tests results (RDm) using HClk=108 and HClk=54 for UDMA4 are 59.8 MB/s on MK1634GAL. - Minimum HClk is limited by tACKENV specs, using current settings it is 54 MHz for UDMA4,UDMA3 and 43 MHz for UDMA2,UDMA1,UDMA0.

2016-05-15iPod Classic: prepare i2c and PMU for bootloaderCástor Muñoz
When the bootloader starts only IRAM is available, the first task is to ask the PMU to verify if the iPod has previously been hibernated by OF. Due to memory limitations, the kernel cannot be used on this stage. This patch modifies I2C and PMU low level functions to not to depend on kernel (removes mutexes, and uses HW timer instead of current_tick), actual kernel functions are modified to be 'mutexed' wrappers of the new functions.

2016-05-14dx90: fix spurious button eventsAmaury Pouly
The kernel on this device reports nonexistent key presses, in particular it reports right presses when pressing the left button... Since when it happens, the right press comes after the left one, the new code simply ignores any right press when the left button in pressed. Change-Id: Ib6ced02682d9cecf4c7f6c58834907a667419cd7
2016-05-14Manually unboost if not using boost in test_codecMichael Giacomelli
Right now GUI boost interfers with test_codec running unboosted by varying the CPU frequency. This at least makes it more consistent if run without user input. Change-Id: I121615098d6bd72ccd13c4e665cc2e4d45d7b58c

2016-05-13Add UART suuport for s5l8700 and s5l8701Cástor Muñoz
Add UART support for s5l8700/1 using the UC870X UART controller, actually the functionallity is disabled and must be enabled for each individual target. Tested on iPod Nano 2G (s5l8701), not tested on s5l8700. Change-Id: Ic0f216bb871502d355a70e4b658e536a2c0976a9
2016-05-13iPod Classic: updates for uc8702 driverCástor Muñoz
- Small rework on the UC8702 UART controller to make it compatible with other s5l870x SOCs. Files moved and renamed, many conditional code added to deal with capabilities and 'features' of the different CPUs. - A couple of optimizacions that should not affect the functionality.

2016-04-08qeditor: port to the new hwstub library and add featuresAmaury Pouly
This commit adds support for the version of the hwstub library, which requires a lot of changes. It also adds some editing features, such as register access and much better editing of fields using the mouse (double click on a field to be able to resize and move it).

2016-04-08regtools: add register access to soc descAmaury Pouly
Registers (and variants) can now specify the type of access supported: - unspecified: for variant means same as register, for register defaults R/W - read/write - read only - write only Backward compatibility is preserved by setting access to unspecified by default. Change-Id: I3e84ae18f962a45db62f996a542d08405d05b895
2016-04-08hwstub: port hwstub_shell to the new libraryAmaury Pouly
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

2016-04-08hwstub: rewrite and expand libraryAmaury Pouly
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
