Occasional ContributorAgilex 5 - HPS first - u-boot stuck if rebooting
Hello, I have problem after reboot of my system (reboot in linux console or press HPSrst button on AXE5-Eagle devboard), or if I fit fpgacore.rbf from u-boot twice, than boot from emmc stuck on: ...

AXE5_EAGLE # run fitfpga 2568192 bytes read in 125 ms (19.6 MiB/s) ...FPGA reconfiguration OK! AXE5_EAGLE # md.l 0x028000070 1 28000070: 00000000 .... AXE5_EAGLE # run fitfpga 2568192 bytes read in 124 ms (19.8 MiB/s) ...FPGA reconfiguration OK! AXE5_EAGLE # md.l 0x028000070 1 <here it freezes>
fitfpga is defined as:
fitfpga=load mmc 0:1 $loadaddr d/design.core.rbf ; dcache flush ; fpga load 0 $loadaddr $filesize ; bridge enable;

Occasional Contributorat 0x02800070 should be FPGA register - USB switch reset register.
So it seems that LWH2F bridge not work, if fpga.core is fitted twice.
Other addresses from LWH2F bridge address pool does not work too (also stucks uboot).
