mb/lenovo/{t60,r60}: Add ThinkPad R60 support as variant board
- This port should be Reclaim Your Freedom compliant (not certified yet). - Untested on boards with external Radeon graphics adapter. - Some columns on the left-most side of display are completely black on 1400x1050 IPS display[1]. Display works fine on Linux. I don't know why it appears like that. So far it has been observed only with native graphics initialization. - Only GRUB2 and SeaBIOS payloads tested for now. - 2504 docking station USB doesn't work under Linux. Can detect pendrive in GRUB2 payload. - Sometimes it takes 20s of "pretending it's powered off" to run coreboot code. Issue is payload agnostic. Probably caused by missing one capacitor on my unit.

+# Lenovo Thinkpad R60
+
+Untested on boards with external Radeon graphics adapter. If you have such
+board, proceed at your own risk and document if it does work.
+
+## Flashing instructions
+
+### External flashing
+
+The flash IC is located at the bottom center of the mainboard. Access to
+the flash chip is blocked by the magnesium frame, so you need to disassemble
+the entire laptop and remove the mainboard. The flash chip is referenced as U49 in
+the schematics and in the boardview.
+
+![](r60_chip.jpg)
+
+To disassemble the laptop, follow the [Hardware Maintenance Manual](https://thinkpads.com/support/hmm/hmm_pdf/42x3749_02.pdf).
+
+### Internal flashing on Vendor BIOS
+
+This [method](https://gist.github.com/ArthurHeymans/c5ef494ada01af372735f237f6c6adbe) describes a way to install coreboot with vendor firmware still
+installed on the Lenovo Thinkpad X60. It is reported to also work in Thinkpad
+R60, with the only difference being the board target you build coreboot for.
+
+### Flashing on coreboot
+
+Default configuration of coreboot doesn't feature any flash restrictions
+like the vendor firmware, therefore flashrom is able to flash any rom without problems.
+
+## Things tested and working in Linux 5.3:
+
+- Intel WiFi card
+- Suspend and resume
+- Native graphics initialization. Both legacy VGA and linear framebuffer work
+- GRUB2 2.04 and SeaBIOS 1.12.1 payloads
+- Reflashing with flashrom (use flashrom-git as of 17.09.2019)
+- 2G+1G memory configuration working
+- 2504 dock USB ports if not hotplugged
+
+## Things tested and not working:
+
+- 2504 dock hotplugging
+- Black bar at the left side of the screen. Doesn't appear in Linux. See picture at top
+- Sometimes it takes several second to run coreboot. Just wait for it
