This patch sets the PLL of CPU cluster B (BPLL) to 600 MHz. This decreases the boot time of Linux 4.19 by about 8%.
The 600 MHz are inspired by the 600 MHz used for LPLL initialization (came in with commit 9f636a249c1).
Tested on RK3399-Q7 on Haikou base board.
Changes since v1:
- Set clk_core_b parent to BPLL instead of LPLL.
Kudos to Mark Kettenis mark.kettenis@xs4all.nl for spotting this.
