* MIPS: refactor cache loops to a macroPaul Burton2015-01-29-17/+13
| | | | | | | | Reduce duplication by performing loops through cache tags using an assembler macro. Signed-off-by: Paul Burton <paul.burton@imgtec.com> Cc: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: refactor L1 cache config reads to a macroPaul Burton2015-01-29-56/+41
| | | | | | | | | Reduce duplication between reading the configuration of the L1 dcache & icache by performing both using a macro which calculates the appropriate line & cache sizes from the coprocessor 0 Config1 register.

* MIPS: unify cache initialization codePaul Burton2015-01-29-224/+15
| | | | | | | | | | | | | | The mips32 & mips64 cache initialization code differs only in that the mips32 code supports reading the cache size from coprocessor 0 registers at runtime. Move the more developed mips32 version to a common arch/mips/lib/cache_init.S & remove the now-redundant mips64 version in order to reduce duplication. The temporary registers used are shuffled slightly in order to work for both mips32 & mips64 builds. The RA register is defined differently to suit mips32 & mips64, but will be removed by a later commit in the series after further cleanup.

* MIPS: unify cache maintenance functionsPaul Burton2015-01-29-167/+119
| | | | | | | | | Move the more developed mips32 version of the cache maintenance functions to a common arch/mips/lib/cache.c, in order to reduce duplication between mips32 & mips64. Signed-off-by: Paul Burton <paul.burton@imgtec.com> Cc: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: avoid .set ISA for cache operationsPaul Burton2015-01-29-38/+33
| | | | | | | | | | | | As a step towards unifying the cache maintenance code for mips32 & mips64 CPUs, stop using ".set <ISA>" directives in the more developed mips32 version of the code. Instead, when present make use of the GCC builtin for emitting a cache instruction. When not present, simply don't bother with the .set directives since U-boot always builds with -march=mips32 or higher anyway.

| * x86: Implement a cache for Memory Reference Code parametersSimon Glass2015-01-24-0/+464
| | | | | | | | | | | | | | | | | | | | | | The memory reference code takes a very long time to 'train' its SDRAM interface, around half a second. To avoid this delay on every boot we can store the parameters from the last training sessions to speed up the next. Add an implementation of this, storing the training data in CMOS RAM and SPI flash.

| | | | | | | | | | | | | | | | | | | | On some x86 processors (like Intel Quark) the MTRR registers are not supported. This is reflected by the CPUID (EAX 01H) result EDX[12].

It could be either wrong capacity or just a 'Capacity: not available' message. After enabling the debug switch, we can see the scsi inquiry command did not execute successfully. However, doing a 'scsi scan' in the U-Boot shell does not expose this issue. SCSI: Target spinup took 0 ms. SATA link 1 timeout.

So uninitialized contents on the stack were passed to dev_print() to display those wrong information. The symptom were observed on two hard drives (one is Seagate, the other one is Western Digital). The fix is to make sure the AHCI interface is not busy by checking the error and status information from task file register after enabling the port in ahci_port_start() before proceeding other operations like scsi_scan().
