2020-02-17libpayload/corebootfb: Fix character buffer relocationNico Huber
The `chars` pointer references the heap which is part of the payload and relocated along with it. So calling phys_to_virt() on it was always wrong; and the virt_to_phys() at its initialization was a no-op anyway, when the console was brought up before relocation. While we are at it, add a null-pointer check.

2017-08-03libpayload: video: Add support for font scaling with a factorPaul Kocialkowski
This introduces support for font scaling with a factor provided via Kconfig. In practice, the font itself is not scaled at any point in memory and only the logic to determine whether a pixel should be filled or not is changed. Thus, it should not significantly impact either the access time or memory use.

If the framebuffer address is zero the corebootfb_init() function should abort and not attempt to use it for video, otherwise it will likely hang. This was tested by booting on a board that does not have a display attached and includes the previous patch to zero the framebuffer structure in the coreboot tables.

2014-12-30libpayload: video: Make cursor fixup independent of visibilityJulius Werner
The video console runs a video_console_fixup_cursor() function after every printed character to make sure the cursor is still in the output window and avoid overflows. For some crazy reason, this function does not run when cursor_enabled is false... however, that variable is only about cursor *visibility*, and it's imperative that we still do proper bounds checking for our output even if the cursor itself doesn't get displayed (otherwise we can end up overwriting malloc cookies that cause a panic on the next free() and other fun things like that). In fact, there seems to be no reason at all to even keep track of the cursor visibility state in the generic video console framework (the specific backends already do it, too), so let's remove that code entirely. Also set the default cursor visibilty in the corebootfb backend to 0 since that's consistent with what the other backends do. BUG=None TEST=Turn on video console on Big, generate enough output to make it scroll, make sure it does not crash.

2012-11-15libpayload: Always use virtual pointers in struct sysinfo_tNico Huber
We had mixed virtual and physical pointers in struct sysinfo_t. Some being virtual by accident which led to problems when we tried to reinitialize lib_sysinfo after relocating FILO (to get intentionally virtual pointers valid again). I guess this didn't cause much trouble before, as lib_get_sysinfo() was always called with physical addresses being equal to their virtual counterparts. For FILO, two possibilities seem practical: Either, have all pointers in struct sysinfo_t physical, so relocation doesn't hurt. Or, have all pointers virtual and call lib_get_sysinfo() again after relocation. This patch goes the latter way, changing the following pointers for situations where virtual pointers differ from physical: .extra_version .build .compile_time .compile_by .compile_host .compile_domain .compiler .linker .assembler .cb_version .vdat_addr .tstamp_table .cbmem_cons .mrc_cache We could also just correct the accidentally virtual pointers. But, IMO, this would lower the risk of future confusion. Note 1: Looks like .version gets never set. Note 2: .option_table and .framebuffer were virtual pointers but treated like physical ones. Even in FILO, this led to no problems as they were set before relocation.
