2012-07-14hw/sh_serial: Use TARGET_PRIxPHYS rather than %x for physaddrPeter Maydell
Switch a format string from %x to TARGET_PRIxPHYS so that it will continue to work even if target_phys_addr_t is changed to 64 bits in the future. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-12-11Add endianness as io mem parameterAlexander Graf
As stated before, devices can be little, big or native endian. The target endianness is not of their concern, so we need to push things down a level. This patch adds a parameter to cpu_register_io_memory that allows a device to choose its endianness. For now, all devices simply choose native endian, because that's the same behavior as before.

2010-03-18Replace assert(0) with abort() or cpu_abort()Blue Swirl
When building with -DNDEBUG, assert(0) will not stop execution so it must not be used for abnormal termination. Use cpu_abort() when in CPU context, abort() otherwise. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2008-12-07SH4: SCI improvementaurel32
This patch simply implement one register of SH4's SCI := Serial Communication Interface. R2D evaluation board uses SCI for SPI connection. So, Linux kernel for R2D with default configuration causes a QEMU assertion failure when it initializes SPI driver. This patch avoids it and reduces the kernel config modification work for QEMU. Completing SCI implementation task is left. Other board support is desirable to confirm this task, which uses SCI for a serial terminal.

2008-12-07SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).balrog
Main purpose of this is to delete *physical = address & 0x1fffffff; at target-sh4/helper.c:449, using new mmio rule introduced by #5849 This masking is a nice trick to realize P4/A7 duality of SH registers. But, IMHO, it is logically wrong. Most of SH4 cpu control registers in P4 area(0xfc000000...0xffffffff) have one more address called A7 which is usually P4 address with upper 3bits masked. This is an address only appears in TLB's physical address part. Current code use trick writing drivers as if they are really in A7 (that's why you see many *_A7 in hw/sh*.c), and using translation P4 to A7.

This patches makes SH serial emulation use qemu_irq in its interface. * hw/sh.h (sh_serial_init): Take qemu_irq, not intc_source. * hw/sh7750.c (sh7750_init): Adjust. * hw/sh_intc.c (sh_intc_set_irq): Don't assert or deassert irq more than once. * hw/sh_serial.c (sh_serial_state): Use qemu_irq, not intc_source.
