From the HPS side the H2F bridge lives at address 0xC000_0000 so the stuff you connect to it would be offset by that amount when you go to access it from the HPS.

By the sounds of it the address width of your component is 32-bit and that's why it is taking up such a large range. The H2F bridge can only access a total span of around 1GB so you'll need to make the address width of your custom component less than 30-bit. Most peripherals have a handful of registers so they don't typically require a large address span.
