* hw/mips: Remove exit(1) in case of missing ROMPavel Dovgalyuk2020-10-171-5/+3Star
| | | | | | | | | | | This patch updates MIPS-based machines to allow starting them without ROM. In this case CPU starts to execute instructions from the empty memory, but QEMU allows introspecting the machine configuration.

* hw/mips: Simplify code using ROUND_UP(INITRD_PAGE_SIZE)Philippe Mathieu-Daudé2020-10-171-2/+1Star
| | | | | | | | | | | Instead of using a INITRD_PAGE_MASK definition, use the simpler INITRD_PAGE_SIZE one which allows us to simplify the code by using directly the self-explicit ROUND_UP() macro.

* hw/mips/fuloong2e: Set CPU frequency to 533 MHzPhilippe Mathieu-Daudé2020-10-171-1/+6
| | | | | | | | | | | The CPU frequency is normally provided by the firmware in the "cpuclock" environment variable. The 2E board can handles up to 660MHz, but be conservative and take the same value used by the Linux kernel: 533 MHz.

* load_elf: Remove unused address variables from callersBALATON Zoltan2020-09-261-4/+4
| | | | | | | | | | | | | | | | Several callers of load_elf() pass pointers for lowaddr and highaddr parameters which are then not used for anything. This may stem from a misunderstanding that load_elf need a value here but in fact it can take NULL to ignore these values. Remove such unused variables and pass NULL instead from callers that don't need these.

* hw/mips/fuloong2e: Convert pointless error message to an assert()Philippe Mathieu-Daudé2020-09-091-4/+1Star
| | | | | | | | | | | | | Displaying "vt82c686b_init error" doesn't give any hint about why this call failed. As this message targets developers and not users, replace the pointless error message by a call to assert() which will provide more useful information.
