2023-01-13jz47xx: Add support for INIT regionSolomon Peachy1-1/+1
Change-Id: I100cd661e9b1225167463542800c6aafbc3c17b3
2022-10-17mips: consolidate exception handling, add exception backtracesAidan MacDonald1-74/+0
Merge the x1000 and jz47xx exception handling code since they use the same exception vectors and handlers. The interrupt handler is now called from the common exception vector, but remains separate for each board since they have different IRQ layouts. The new exception handler can provide a stack traceback from the interrupted code, rather than the (uninteresting) caller traceback displayed by panicf. This allows you to see what led up to a null pointer deref or division by zero, which makes it _much_ easier to track down errors that occur in common leaf functions like strcmp.

2020-09-03mips: Heavily rework DMA & caching codeSolomon Peachy1-8/+7
Based on code originally written by Amaury Pouly (g#1789, g#1791, g#1527) but rebased and heavily updated. Change-Id: Ic794abb5e8d89feb4b88fc3abe854270fb28db70
2020-07-24[4/4] Remove HAVE_LCD_BITMAP, as it's now the only choice.Solomon Peachy1-2/+1
Note: I left behind lcd_bitmap in features.txt, because removing it would require considerable work in the manual and the translations. Change-Id: Ia8ca7761f610d9332a0d22a7d189775fb15ec88a

2013-03-11jz4740: a few minor fixesMarcin Bukat1-1/+1
This was spotted while playing with qemu-jz: 1) rockbox reads TECR and TESR which are described as write-only registers. Datasheet doesn't mention what happens if they are readed. Apparently this doesn't have fatal side effects. It comes down to two defines from jz4740.h __tcu_stop_counter(n) and __tcu_start_counter(n) which use read-modify-write sequence. 2) rockbox accesses out of bound offset 0xd4 in DMA memspace. It comes from dis_irq() in system-jz4740.c. NUM_DMA is 6 but DMA channels are 0-5 so (irq <= IRQ_DMA_0 + NUM_DMA)) bound check is wrong. This are *NOT* tested on device.
