2015-01-09Primitive memory testDavid Hendricks
This adds a generic primitive memory test. We should look into using tests in src/lib/ramtest.c, but they seem to rely too heavily on x86 asm and this test has been useful on multiple ARM platforms.

2014-05-05lib/hexdump: Use `size_t` for length parameter of `hexdump32()`Paul Menzel
In the signature of the function `hexdump32()` it does not make sense to represent a length, assumed to be positive, as a signed integer. With this change, it is no longer necessary to cast a pointer to unsigned long when passing it to `hexdump32()`.

2014-01-13lib: Make log2() available in romstage on ARM, not just x86Alexandru Gagniuc
On x86, log2() is defined as an inline function in arch/io.h. This is a remnant of ROMCC, and forced us to not include clog2.c in romstage. As a result, romstage on ARM has no log2(). Use the inline log2 only with ROMCC, but otherwise, use the one in clog2.c.

2013-06-10ramtest.c: Add silent ram_checkAlexandru Gagniuc
In some cases, we want a ram_check that does not die and does not clobber the terminal with useless output that slows us down a lot. Usage examples include Checking if the RAM is up at the start of raminit, or checking if each rank is accessible as it is being initialized. As with all other ram_checks, this is more of a "Is my DRAM properly configured?" test, which is exactly what we want for something to use during memory initialization.

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

2012-07-24Implement stack overflow checking for the BSPRonald G. Minnich
Previous patches implemented stack overflow checking for the APs. This patch builds on the BSP stack poisoning patch to implement stack overflow checking for the BSP, and also prints out maximum stack usage. It reveals that our 32K stack is ridiculously oversized, especially now that the lzma decoder doesn't use a giant 16K on-stack array. Break the stack checking out into a separate function, which we will later use for the APs. CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8 To test failure, change the DEADBEEF stack poison value in c_start.S to something else. Then we should get an error like this: Stack overrun on BSP.Increase stack from current 32768 bytes CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000 Separate the act of loading from the act of starting the payload. This allows us better error management and reporting of stack use. Now we see: CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8 Tested for both success and failure on Link. At the same time, feel free to carefully check my manipulation of _estack. Change-Id: Ibb09738b15ec6a5510ac81e45dd82756bfa5aac2 Signed-off-by: Ronald G.
