* MIPS: Malta: convert to generic boardPaul Burton2014-04-20-0/+3
| | | | | | | This patch converts the MIPS Malta development board to make use of the generic board code now that it is supported on MIPS. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* malta: set CONFIG_SYS_BOOTM_LEN to 64MBPaul Burton2013-11-26-0/+1
| | | | | | | Allow a larger kernel binary to be decompressed - the default 8MB can become limiting on a Malta. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* malta: correct UART baudratePaul Burton2013-11-26-1/+1
| | | | | | | | | | CONFIG_SYS_NS16550_CLK specifies the rate of the clock 16x the baud rate. The SMSC FDC37M81x datasheet states that a divider of 1 results in a UART at 115200 baud, thus the x16 clock rate is 115200 * 16. Previously the divider was left at 0 which led to a rate of 38400 baud regardless of CONFIG_BAUDRATE or the baudrate environment variable. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* malta: use unmapped flash base addressGabor Juhos2013-11-15-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The physical base address of the NOR flash is 0x1e000000 on the Malta boards. The hardware also maps the first 4MiB of the flash into the 0x1fc00000-0x1fffffff range. Currently, U-Boot uses the mapped address to access the flash, which does not work in recent qemu versions. Since commit a427338b222b43197c2776cbc996936df0302f51 (mips_malta: correct reading MIPS revision at 0x1fc00010) writing to the mapped address space causes a CPU exception. Due to the exception, U-Boot hangs during boot when it tries to detect the CFI flash chip. Use the correct physical address for the MALTA_FLASH_BASE constant to fix the problem. In order to avoid relocation problems, also update the CONFIG_SYS_{TEXT,MONITOR}_BASE constants. The change makes it possible to start U-Boot on a Malta board emulated with Qemu 1.6.1 and 1.7.0-rc0. It also works on older versions (tested with 1.1.1, 1.2.2, 1.4.2, 1.5.3).

* malta: define CONFIG_MEMSIZE_IN_BYTESGabor Juhos2013-11-09-0/+2
| | | | | | | | | | | | | | The memsize environment variable must contain the memory size in bytes on the Malta board. Otherwise Linux will use wrong memory size which causes a kernel panic. Define CONFIG_MEMSIZE_IN_BYTES in malta.h to avoid that.

* malta: store environment in flashPaul Burton2013-11-09-6/+9
| | | | | | | | | Allow the environment to be stored in the monitor flash of a Malta board. The environment is stored in the final 128KB of the flash, which both leaves the majority of the flash available for U-boot code and also matches the location which YAMON uses.

* malta: enable RTC supportPaul Burton2013-11-09-0/+5
| | | | | | | | | This is actually required in order for a Linux kernel to boot successfully on a physical Malta board. Without enabling the RTC, a Malta Linux kernel will get stuck in its estimate_frequencies function on boot. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* malta: remove cache size definitionsPaul Burton2013-11-09-4/+0
| | | | | | | | | | These will now be detected at runtime, allowing a single U-boot configuration to function correctly with different bitstreams. Without this you may need to re-configure, re-build and re-flash U-boot to your Malta if you flash a new bitstream with a different cache configuration to your old bitstream.

* malta: enable CONFIG_PCNET_79C973, PCNET_HAS_PROM, CONFIG_CMD_DHCPPaul Burton2013-11-09-0/+3
| | | | | | | | | | | | | This model of the pcnet is used in current Malta boards, at least in the Malta-R rev 3. Enable support for it. The Malta also has the ethernet controller PROM containing its MAC address, so enable support for that in order to read that MAC address. DHCP is a very useful feature to have available for many networks, enable support for it also. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* malta: support for coreFPGA6 boardsPaul Burton2013-11-09-1/+3
| | | | | | | | | | | | | | | | | | | | | This patch adds support for running on Malta boards using coreFPGA6 core cards, including support for the msc01 system controller used with them. The system controller is detected at runtime allowing one U-boot binary to run on a Malta with either. Due to the PCI I/O base differing between Maltas using gt64120 & msc01 system controllers, the UART setup is modified slightly. A second UART is added so that there is one pointing at the correct address for each system controller. The Malta board then defines its own default_serial_console function to select the correct one at runtime. The incorrect UART will simply not function. Tested on: - A coreFPGA6 Malta running interAptiv and proAptiv bitstreams, both with and without an L2 cache. - QEMU. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
* qemu-malta: rename to just "malta"Paul Burton2013-11-09-0/+113
This is in preparation for adapting this board to function correctly on a physical MIPS Malta board. The board is moved into an "imgtec" vendor directory at the same time in order to ready us for any other boards supported by Imagination in the future.
