Marc Zyngier 22d5fd1d20 PCI: amlogic: meson: Don't use FAST_LINK_MODE to set up link ... [ Upstream commit 87dccf09323fc363bd0d072fcc12b96622ab8c69 ] The vim3l board does not work with a standard PCIe switch (ASM1184e), spitting all kind of errors - hinting at HW misconfiguration (no link, port enumeration issues, etc). According to the the Synopsys DWC PCIe Reference Manual, in the section dedicated to the PLCR register, bit 7 is described (FAST_LINK_MODE) as: "Sets all internal timers to fast mode for simulation purposes." it is sound to set this bit from a simulation perspective, but on actual silicon, which expects timers to have a nominal value, it is not. Make sure the FAST_LINK_MODE bit is cleared when configuring the RC to solve this problem.
